Great place to stay. About 10 to 15 mins walk from Belsize Park tube station, so about 10 mins on the tube to the city. Comfortable bed, light, airy room. It's quite quiet too. The shower is a nice rain shower. June was a very accommodating, welcoming and helpful host. I felt comfortable staying there. Had a cheeky afternoon nap without getting in the way of her plans! Hampstead Heath itself was great too. Went for a few runs there in the spring sun. There's the Park Run there every Saturday 9 am. Lovely Hampstead cafes on your door step as well. Easy access to Camden's lively night life too eg Green Note or Roundhouse. Take it!
