London vs Madrid

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.

Madrid

Madrid has a continental Mediterranean climate with hot, dry summers and cool winters. The high altitude means cold winter nights despite sunny days.

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.

Madrid

Madrid has one of the best public transport systems in Europe. The metro is extensive, clean, and efficient. The historic center is very walkable.

Walkability: Excellent in the center — Sol, Gran Via, Plaza Mayor, the Royal Palace, and Retiro Park are all within comfortable walking distance of each other.
