We had a very lovely stay at Justin & Xavier's place in Brixton. We were not there a good bit of the week (so much sightseeing!) but the time we were at the flat was great. Very clean, modern home. Plenty of room for a "shared" unit, it almost felt like a private place since we had our own bathroom, kitchenette, and floor. The two cats Toto & Lolo are sweet and love getting a bit of attention. Justin & Xavier are very kind people -- always with smiles and a little advice on transit, etc if you ask.
Brixton underground station is about a 10 min walk from the place, bus stops are everywhere. Very convenient for going just about anywhere in or around London.
Wouldn't hesitate to book again!
