Excellent location, especially if you plan to just walk most places on your visit. Definitely use Sarah’s directions to the flat, cause google will take you up the “new steps” and that’s not a fun haul from the train station when you’re carrying bags. 1 bathroom for a lot of people did get a little hectic, but we made it work, basic cooking items (pans/etc) made it easy to cook meals as a group. Stairs to the flat may not be good for small children or people with mobility issues, but otherwise, this is a great place to stay and enjoy while you’re exploring Edinburgh!
