Andrey is a very friendly and helpful host and the apartment is very well located very close to Canary Wharf and two different DLR stations.
The room is very spacious and the own bathroom is very convenient to have.
Cleaning could be improved but not serious issues, and if you are not extremely sensitive to noise you should be OK, but bear in mind the room is located at street level (in a dead end, though) and next to the main building lift.
Smoking is allowed (in the garden).
