We had a lovely time in London and Katie (didn't meet Simon) was part of that. Location, like everyone said, is in walking distance of the tube and there are tons of eating/drinking places nearby. The bread and French press she provided in the morning definitely hit the spot. The wifi was a bit spotty but if you don't mind that, no issues there :). Be sure to try Tayyab (Paskistani/Indian food). Katie recommended it in her suggested places book and it was a hit.
