Adam has a lovely flat, very close to the action in Edinburgh city centre. We used his flat for 3 nights as a base for the festival and had a great time. The room is comfortable, breakfast was provided and the area is nice. Parking for non residents is available, but it's a 15-20minute walk from the flat, as its on-street and all the locals know it and get there first!
Although we didn't meet Adam, his communication was prompt, helpful and polite.
I would definitely recommend staying here.
