Lily's place is good and well maintained. The house is also in a good spot: close to Rotherhithe station; nice view of the River Thames; nice view of London Bridge which you can follow the Thames Path to get to. Lily also keeps the place clean and tidy.
As for the room itself (Room 2), Its spacious enough for a single person with a desk and chair which is good for a temporary work-from-home station or other admin work (Very good wifi too). It also has direct access to the backyard. The only issue I had, was that its directly below Room 3, which the ceiling in this room does not do a good job of insulating the noise from above. Otherwise, its a very good room.
