I recently stayed here with a friend for 4 nights and loved Rufus's place. It was really homely and the place was spotless when we arrived. Check in and check out was also very easy. Everything we visited was walkable from the apartment.. Arthur's Seat, the Royal Mile, the Castle, great pubs and restaurants. You won't need a car at all to enjoy all the Edinburgh hot spots. Would definitely recommend to my friends who were looking for a place to stay in Edinburgh.
It was great having the Netflix too when we were all whisky'd out and were needing a quiet night in!!
