We ( a family of four) stayed for a long weekend in London and Geoff's place was just perfect at all points : very easy to reach from the airport (Gatwick), very central to visit all the main attractions in London.
The place is clean and confortable. 2 mns walk from the underground.
Geoff provides a lot of very usefull information about the place's area and what it is to see around. He also replies within minutes to your questions which is very enjoyable.
I would definitely recommand this place.
