Barbara was very responsive. I could get her reply within 10min whenever I sent messages to her. I arrived in London very early in the morning, but she welcomed me in person and let me check in the room so that I could take a rest after the long flight. The room was exactly as described. It was well maintained, clean, and had all I needed. The neighborhood was so nice and quiet, and seemed to be very safe. You can walk to two different tube stations, whole foods, and many other stores. Highly recommended.
