Central London has several practical bases, but each favors a different type of trip.
Westminster for landmarks
Westminster is practical for classic first-trip sights.
South Bank for river access
South Bank works well for Thames walks and cultural venues.
Covent Garden for theatre and evenings
Covent Garden suits travelers who prioritize the West End, dining and a central evening atmosphere.
Check the station, not only the postcode
A useful Tube or rail station can matter more than a famous street name.
