My wife and I stayed at Edson's flat for a month and it was exactly as other described: clean and cosy, with a well equipped kitchen and a big bedroom with a confy bed. It had lots of light, given that it is on the top floor and has windows from all sides. The building is not exactly beautiful from the outside, but it's in a very quiet neighborhood just facing the park - and inside has everything we needed. The flat is also just a few minutes walk away from the Bethnal Green station (Central Line) and Shoreditch is just 10min away!
All in all, great place to stay - highly recommend it.
