Downtown London

London doesn't have a single downtown. The City of London — the 'Square Mile' — is the historic financial core, with its own local government, Roman wall fragments and lanes of medieval width squeezed between glass towers. Two miles west, the West End is the city's entertainment and shopping centre.

Between them run the Thames, the South Bank's cultural institutions and one of the densest transit networks on earth. A good day here means walking from St Paul's across the Millennium Bridge to Tate Modern, then following the river toward Westminster. The catch is cost: London is one of the most expensive cities in Europe to sleep, eat and rent in, so the free museums, parks and riverside walks do a lot of the work.

The districts

Landmarks worth your time

• St Paul's Cathedral. Christopher Wren's domed masterpiece with climbable galleries. Sightseeing is closed on Sundays, when it is open for worship only.
• Tower of London and Tower Bridge. A royal fortress that holds the Crown Jewels, beside the famous bascule bridge.
• Sky Garden. A free public garden at the top of a City tower — book a slot in advance.
• Leadenhall Market. An ornate Victorian covered market among the office towers.
• Borough Market. A historic food market just across London Bridge.
• Tate Modern. A free modern art museum in a converted power station.
• British Museum. Free, in Bloomsbury, with two million years of human history under one glass-roofed courtyard; booking a free timed slot helps at busy times.
• National Gallery. Free, on Trafalgar Square, with European paintings from the Middle Ages to the early twentieth century.

A perfect day downtown

Morning. Arrive at St Paul's as it opens for sightseeing and climb to the galleries before the queues build. Walk across the Millennium Bridge to Tate Modern for an hour with the free collection, then follow the riverside to Borough Market for an early lunch before the office crowd arrives.

Afternoon. Walk west along the South Bank past the Southbank Centre's concrete terraces and the second-hand book stalls under Waterloo Bridge, and cross Westminster Bridge for the classic view of Parliament. Head up Whitehall to Trafalgar Square and spend the rest of the afternoon in the National Gallery, or duck into the narrow lanes of Covent Garden.

Evening. See a West End show; the official half-price booth in Leicester Square and theatres' own day-seat schemes are the best routes to cheaper same-day tickets. Eat a pre-theatre set menu in Soho or Covent Garden, then finish in an old pub. On a weekday, swap the theatre for Leadenhall Market and the Sky Garden at dusk.

Eat and drink

Borough Market and Leadenhall Market are the obvious starts. Soho and Covent Garden pack in everything from Chinatown's dim sum to tasting menus, and Shoreditch is strong on casual and late-night food. Pubs remain the best value for a sit-down meal in the City.

London eats globally. Brick Lane, a short walk east of the City, is known for Bangladeshi curry houses and round-the-clock bagel bakeries, Chinatown's Gerrard Street is the place for roast duck and dim sum, and Old Spitalfields Market fills with street-food stalls. A Sunday roast in a pub is a weekend ritual worth booking. To eat well cheaply, look for set lunch menus, street food and supermarket meal deals, and remember that pubs and restaurants serving alcohol must give you tap water free if you ask. Many City pubs and cafés close or shorten their hours at weekends, when the office workers stay away.

Getting around

The Underground's Bank and Liverpool Street stations are major City interchanges, and the Elizabeth line links Heathrow, the West End, the City and Canary Wharf. Buses, Santander Cycles hire bikes and river boats complete the network. Transport for London runs the Tube, buses and the Elizabeth line, and a contactless card or phone works on all of them as well as on most National Rail services within London. Buses don't accept cash. The Night Tube runs on several lines on Friday and Saturday nights, and night buses cover the rest.

From Heathrow, the Elizabeth line and the Piccadilly line run into central London, and the Heathrow Express runs non-stop to Paddington. Gatwick is served by the Gatwick Express to Victoria and by Thameslink trains through London Bridge, Blackfriars, City Thameslink and Farringdon. The DLR reaches London City Airport from Bank, the Stansted Express runs to Liverpool Street, and Thameslink serves Luton via Luton Airport Parkway. Eurostar trains leave from St Pancras International. In the centre, walking between stations is often quicker than changing lines. Driving makes little sense: the Congestion Charge applies across the centre, the Ultra Low Emission Zone covers all of Greater London, and parking is scarce and expensive.

Where to stay

Stay in the West End around Covent Garden and Soho for theatres, restaurants and late nights, accepting noise and small rooms. Bankside and the South Bank put you on the river, close to Tate Modern and Borough Market, with easy walks into both downtowns. The City and Aldgate suit business travellers during the week, and the quiet streets mean City hotels can be better value at weekends. Bloomsbury and King's Cross are central, a little calmer and ideal if you arrive by Eurostar or want to be near the British Museum. Shoreditch is the pick for nightlife and a younger crowd, and Westminster and St James's for classic sights and royal parks.

Living downtown

Few people live in the City itself, though the Barbican Estate is a landmark exception. Clerkenwell, Shoreditch and the South Bank fringe offer flats with short commutes. Rents are among Europe's highest. Expect period conversions with steep stairs, mansion blocks in Bloomsbury and Marylebone, and new-build towers with concierge services in Aldgate, the South Bank and around King's Cross.

For most tenancies in England, deposits are capped at five weeks' rent and must be protected in a government-approved scheme, and most letting fees charged to tenants are banned. Landlords must check your right to rent before you move in, and tenants usually pay council tax and utilities on top of rent. England's private rental rules are being reformed under the Renters' Rights Act, which moves tenancies onto a rolling basis and ends 'no-fault' evictions, so check the current rules before you sign. Central living suits people who walk to work and value culture on the doorstep; households wanting space and value usually look further out on the Tube or Overground.

Doing business downtown

The City is a global centre for banking, insurance and law, with Canary Wharf as a second financial hub. The West End is retail and hospitality's flagship district, with high rents and very high footfall.

Around those cores, each district has its own business character. Mayfair and St James's are home to investment managers and private equity firms; Holborn and Farringdon, often called Midtown, mix law firms, professional services and media; King's Cross has become a campus for big technology and life-sciences companies; and Shoreditch remains the startup quarter. Newer towers around London Bridge and Southwark add modern office floors south of the river. Oxford Street, Regent Street and Bond Street carry flagship retail, while City shops depend on weekday office trade. Companies are registered with Companies House and taxes handled by HMRC.

Seasons and weather

London's climate is mild and changeable rather than extreme. Late spring and summer bring long, light evenings and the best weather for river walks and park picnics, with occasional heatwaves that make the deeper, older Tube lines uncomfortably warm. Autumn is often crisp and bright, and winter is grey and damp, with darkness by late afternoon in December, but rarely very cold; snow is unusual and short-lived. Rain can arrive in any month, usually as showers rather than downpours. Pack layers, a light waterproof and comfortable shoes for long days on foot.

Safety and practicalities

Central London is generally safe, but pickpockets work Oxford Circus, Leicester Square, Covent Garden and crowded Tube carriages, and phone snatching by thieves on bikes is common, so keep your phone away from the kerb. Use licensed black cabs or booked minicabs rather than unbooked offers on the street. Many older Tube stations have no step-free access, so check Transport for London's accessibility information before you travel; the Elizabeth line is step-free throughout. Stand on the right on Tube escalators and walk on the left. Plugs are the three-pin Type G, and tap water is safe to drink.
