My friend and I so loved staying at Sara's flat near Broadway Market. The location is amazing if you're up for a bit of walking. You're in a quiet residential court with a garden, trees and the lovely canal steps away, yet just a block or two from the market with plenty of shops and cafes. London Fields and Victoria Park are close. It's a few mins walk to any buses, and no tube is very close, but it's decently connected, and it's great if you're looking for a place to *be* in London, rather than just a crashpad.
The flat is lovely, my bed was great and we seemed to have everything we needed. Of course, the family was not there while we stayed, but Sara was communicative and really generous. My favorite place I've stayed in London so far. Highly recommended!
