I have stayed there for two weeks and I can say that Toni's place is really exceptional, from the finishing to the location.
This tiny two stories apt is perfect for a single and couple. The place has been recently fully renovated (the bathroom is very enjoyable, something which is very difficult to find into normal airb&b apt).
Location (Gipsy Hill/Crystal Palace) is calm and lively at night. From Gispy Hill train station a direct train reaches the city center (London Bridge) in 30 min.
Toni is really very pleasant and ready to help anytime.
