My fiancé and I really enjoyed our time at Castletown! Mark was helpful in giving us directions to take the underground to the house. He greeted us in the lobby when we arrived and had upgraded us to a larger flat on the ground floor. It was nice, comfortable, had a small kitchen with some seasonings and oil so we could cook. The bed was comfortable and Mark took care to show us around the flat before leaving. He even gave us local tips on jazz spots and how to get there before leaving. Everything was highly accessible in the neighborhood or tube, which was a 5 min walk from our flat. I would highly recommend staying here if you want a centrally located comfortable place to stay in London.
