We enjoyed our stay at Darya's apartment. It was very spacious, the beds were comfortable, and Darya was very responsive and kind. We enjoyed the location, too - close to cafes and restaurants, a crepe shop, grocery stores/pharmacies, etc. It was also very close to multiple bus lines that can take you to central London quickly.
If you are planning on doing much work from the apartment during the day, we would probably not recommend it because the wifi was a bit spotty (and did not work in the rooms in the basement), and you can hear footsteps and noise from upstairs quite easily. It is, however, very quiet at night.
