The flat is very comfortable and very close to the centre of Edinburgh whilst still being on a nice quiet street with good local shops. Parking is nearly all permit-based or hourly parking but it is free between 17:30 and 08:30 the next morning so manageable if you move your car around.
We were there to visit the university, see the Fringe and the Tattoo and we couldn't have been happier with where we were based. It was a lovely trip.
