Location! This apartment is central to everything in London. 5 minute walk to the tube and you can access the Piccadilly line and the central line. Walking distance to seven dials, soho, the river front, Mayfair (if you don't mind longer walks).
Peter, this host is very friendly and always quick with his response to inquiries. We didn't have any issues, so only spoke with him one time to get instructions on picking up our key. Very easy to get checked in to the apartment.
The apartment itself is basic, but it had everything we needed/wanted. Perfect base to explore London and not spend so much on hotel services.
I would definitely stay here again.
