Highly recommended! The location is great -- just a five minute walk to the Belsize Park tube stop on the Northern Line. Charming, quiet neighborhood with a grocery store, restaurants, and other essentials nearby. The studio is just as pictured (though a bit smaller in "feel" than the pictures would suggest). Clean, modern, and quiet. The mattress is comfortable, though it didn't seem to me to be either king-sized or memory foam (as advertised). (It was what in America would be called queen-sized; perhaps these king/queen designations are different between England the USA where I'm from.) The bathroom is small but clean and everything works great. The shower might be a little bit too small/narrow for a very large guest to use comfortably.

All in all, a wonderful place to stay. For the location and the price, you'd be very hard pressed to do better!
