Stuart's place is in an ideal location, just adjacent to the Royal Mile that leads to Edinburgh Castle. Most of the immediate restaurants and shops are aimed at tourists, but you can still find good quality experiences, and it's easy enough to walk beyond the touristy area or go hiking up to Arthur's Seat (recommended).
The place itself is large, comfortable, offers nice views, and has everything you'll need. Stuart met us as we approached from the train station, and gave us some great dining advice for the evening.
We loved our stay, and would recommended it to anyone visiting here.
