The stay at Sara's place was perfect- it's situated in a quiet neighbourhood, that is very close to train, bus stops that go everywhere in London. There is an university campus nearby, so naturally there are a lot of bars and places for a drink or a snack.
The flat is quite spacious, bright and nicely decorated. It's clean and comfortable (especially the bathroom, which looks completely new)!
Sara is very helpful and she answered every question we had in an instant. We would definitely recommend staying here!
