Benjamin is a very nice and easy-going host, the house is super clean, he changed our towels set twice, which was great. Location-wise the flat is pretty close to the tube and walking distance to the main parks and museums.
The flat and room is exactly what it is advertised - simple, comfortable enough, hot water and full kitchen.
Apartment is an one bedroom, the guest sleeps in the bedroom and Benjamin in the living room, despite the guest having fully access to the living during the day, which worked pretty well for us.
