The airbnb listing is very misleading. Amber named it contemporary home with pictures of the entire flat on the front page. But what you get is a very small room on the first floor.
Amber allows one to use the kitchen and the living area on the ground floor but sometimes it really is not convenient as she needs to use it for yoga in the morning and her daughter plays music on the second floor.
Upon arrival, when I realized it is a shared space with Amber I asked for the booking period to be reduced but the request was rejected.
To be fair the location is very good and Amber is a pleasant person to deal with but you can get a studio or one bedroom with the entire space to yourself for the same price in Central London(perhaps not in Belgravia but in South Kensington or Soho)
I see now Amber has changed the front page picture of the listing to the actual bedroom instead of the living room so I hope less people will get mislead. If you come to London by yourself spending most of the time outside then it is fine otherwise I don't recommend if you are travelling in duo or intend to spend some time in the flat.
