The host is the nicest guy, always ready to help!
The room is cozy and the bed is comfortable (plus having a mirror, a tv and, in my case, a desk, contributed to the overall environment of the room)
The kitchen is more spacious than it looked on the pictures.
I felt safe with the system of the doors and liked the fact that I didn't need to carry a card/keys around.
The house is located in a cool area with lots of good places to eat/going for a drink around, and bus stations to the most touristic points almost in front of the door. I would definitely stay there again in my next visit to London and would recommend it to a friend.
