We didn't feel comfortable. There are a lot of details that are different from Airbnb advertisement : walking distance to royal mile is more 30 minutes than 15, the room is noisy because of the street, the floor, shower and furniture are not really clean, the bed is not the one in the picture, the mattress quality is low, and there are marks and small damages on the walls and on the furniture.
But Allan is a great host, really nice and will try to help if needed.
All in all, if you are not noise-sensitive and don't pay attention to details, you can have a lovely time in Allan's room.
