We stayed during the fringe festival and were in walking distance to so many venues. It is around the corner from the Royal Mile which during the fringe was insanely busy, but this street was nice and quiet. Stuart provided a great list of anything and everything you might need, and responded immediately to any queries. It is a four flight climb so if you are not fit, or tire easily, or have lots of luggage it might not be for you! Views from the apt were amazing though - secret gardens behind all the tenements, and across to the Forth and New Town. Highly recommend!
