This was the best (and, well, most expensive) accomodation we ever had in London, and we enjoyed our stay very much. The appartment in Belgravia was brand new and very clean, up to date technique, very good beds. It is 5 min walk to Sloane Sq. underground station and 10 min walk to Victoria train station and 5 min to Victoria coach station. The bed room s are all to the rear and very quiet, and the living room (facing Pimlico Rd.) is well soundproofed. This was our first booking with Sonder, and we needed some time to understand the - perfectly organized - booking system, but communication was very fast, the information given easy to understand; employees of Sonder were very friendly and eager to respond to our wishes. If you need access before 4 p.m. or leave after 11.00, we'd recommend to contact Sonder.
