This is a great place for visiting London, the flat is less than 5 minutes walking distance to Waterloo stations, and actually you do not need to take the metro to visit all the main monuments, it is a nice walk.
The room is confortable, we were 3 in there and it was ok for a few days.
Lucy's daughter is a beautiful and charming girl who taught a few words to my father. And Lucy is a very friendly and wellcoming host and her comments were really useful. So, i would definitely recommend Lucy's place.
