I highly recommend staying in Bianca's place in Hackney. The room was really clean and spacious - very comfortable to work from as well (I work remotely with my company and the wifi was strong and was a nice laptop friendly workspace).
The rest of the house has everything you need and the other guests during my stay were really nice and cool to hangout with.
Bianca was super helpful with everything that I needed and made the stay a very positive experience.
The only thing you should note is that the apartment is right above a street that can get a little loud in the afternoon with kids walking home from school and yelling really loudly, but besides that the location is great if you are looking to stay in Hackney.
