The flat is positioned under the level of the street, but still with some sunlight (as many other flats in the neighborhood), with its own entrance. The location is excellent, with easy access to Victoria station and to shops and restaurants in the area.
Good communication from the host, flat was clean, everything in place. Heating, bathroom equipment and its water heating are older (do not forget to turn it on when you arrive), rest of the flat is well equipped. Bed could be wider.
We have enjoyed our stay, having no problems there.
