London vs Seville

London

London's reputation for rain is somewhat exaggerated — it actually receives less annual rainfall than Sydney, Rome, or New York. However, drizzle is frequent and skies are often overcast. Pack layers and a waterproof jacket regardless of season.

Seville

Seville has a Mediterranean climate with scorching summers and mild winters. The city is famous for extreme summer heat, making spring and autumn the ideal seasons to visit. Winter is mild and pleasant with occasional rain.

London

London's transport network (TfL) is extensive and efficient. Use a contactless bank card or Oyster card for the best fares — a daily cap of £8.10 (Zone 1-2) means you'll never overpay. Paper tickets cost significantly more. The Tube is the backbone, but buses and walking are often better for seeing the city.

Walkability: Central London is very walkable and walking is often faster than the Tube for short distances. The South Bank riverside walk from Westminster to Tower Bridge is one of Europe's best urban walks. Green parks (Hyde Park, St. James's Park, Regent's Park) connect neighborhoods beautifully on foot.

Seville

Seville's old town is compact and best explored on foot. The city has a single metro line, an extensive bus network, a tram, and an excellent public bike-sharing system (Sevici). The historic center is largely pedestrianized.

Walkability: Seville's centro historico is very walkable and largely flat. The main sights are clustered within a 20-minute walk of each other. The pedestrianized streets around the Cathedral and Santa Cruz are delightful. Summer heat is the main obstacle to walking.
