First of all thanks to Matt for the warm hospitality.
The location was perfect for us cos we like the Marylebone area. It is convenient and within walking distance to a lot of nice restaurants and shops and yet it is quiet. Neighbourhoods are nice so we feel very comfortable staying there. The host is also very thoughtful to provide a fan during the hot weather. The biggest positive surprise is the elevator. Given we carry heavy suitcases it makes our lives a lot easier.
The drawback is the tiny bathroom. We will definitely come back again to stay.
