Bella's place is a short walking distance from west hampstead station. And the bus stop is right in front of her house. Bus 139 takes you to Oxford circus and its a 24 hour bus service. Bus 328 brings you to Kensington palace. There are many nice cafes within walking distance along the road. Wet fish cafe is a must try. It's a nice and serene place away from the city buzz.
Bella is a caring host who fully respects your privacy while attentive to the little details. E.g bringing more blankets when the weather turned chilly. A highly recommended place to stay at. We stayed for a week.
