We visited Grant's flat in early June with our two children (ages 11 and 12).
Grant's flat is centrally located in Soho within easy walking distance to excellent restaurants, entertainment, iconic landmarks, and the tube. The place is clean and well kept with comfortable beds. Communication with Grant was excellent. He monitored the status of our international flight arrival just in case of delays and met us at the apartment as planned. Grant is very clear and upfront about the evening noise level outside the apartment; however, we did not find the outside noise level to be unreasonably loud and not any different from staying in a large city. The apartment is located close to bars and clubs and most of the noise was Saturday night. Overall, Grant was a great host with a fantastic apartment.
