The flat is quiet and has an excellent location with nearby tube (South Kensington) and buses to central London. One of the three bedrooms is off the living room. The bedrooms are small but OK for a short stay. The flat is lovely and with a spacious living room and very useful kitchen. The balcony is not usable to sit on as it is small and taken up with A/C machinery.
The owner responded very quickly to messages and dealt with minor problems as needed.
When arriving it is worth realizing that the address is Princes Gate, but it is actually on Exhibition Road, and is next to the V&A museum.
