The location is superb. In a posh area and within a walking distance to Royal Albert Hall.
The keys to the gate and the room are opened by an smartphone app. Therefore, guests need to have a reliable internet connection. If there is a problem with your internet connection, you may not be able to enter the room.
I wish the dry capability of the clothes washing machine to be stronger. I usually set wash and dry in the morning and went out. When I returned to the room, clothes were not completely dry but still a little wet. Therefore, I had to run the second dry again which is frustrating.
