Location wise it really is as perfect as it gets. Literally a few seconds from the Royal mile, and being situated right next to Waverley Station makes getting between the Old and New sides of Edinburgh very easy. Room is exceptionally clean, and comes with all the appliances of a normal home.
The only quirk would be the fact that heating is controlled remotely by the host, which didn't turn out to be a big problem since the host is pretty quick on the response.
