A very excellent location within a few minutes walk of two different underground stations, a few minutes from Hyde Park, and close to bike hiring stations! Ali's place was as described; small but functional, with good heating and natural light. He responded quickly to messages we sent him, including allowing us to check in slightly earlier than stated, and when there was a brief power outage cause by faulty toaster he was incredibly prompt in replacing it and fixing the power! We had a wonderful stay at his place.
