The apartment is very nice, very luminous and well furnished, and corresponds to the pictures. The location in Hampstead is fantastic, only 5 minutes on foot from the Hampstead station and close to the Hampstead Heath park. The surroundings are beautiful, we really had a great stay there. The entry was easy and Lisa was very helpful during our stay, we definitively recommend it.
It is better for two or three people, since the apartment is not very big: we were two adults and two children and the kitchen was a bit small for us. Moreover, the wifi connection was rather poor; Lisa told us that she is going to fix this issue. In the whole, a highly recommendable option.
