This studio is in a great location - very close to Hampstead tube station, a Tesco, and the parks around Hampstead. It's very quiet, especially at night. The bed is also very comfortable, and there's generous storage for clothes and luggage.
The kitchen is very small - you won't be cooking much here, but there are lots of great restaurants just 5 min walk away. There's no central heating, but the hosts have supplied three heaters in the room.
