I stayed at Ann's with a friend for 4 nights and it was one of the nicest airbnb expierences I've had. The rooms are just as shown in the pictures. Very clean, quite privat and very very cozy and homely. There is a bus stop a 3 minutes walk from the house, where busses to the city centre stop every few minutes. Ann serves a filling breakfast in her lovely kitchen and is always available for recommendations on what to do in Edinburgh or local information, etc.
I wholeheartedly recommend staying at Ann's.
