David’s place was great. It was extremely central in Edinburgh, and the apartment was very comfortable (and included nice touches).
Couple of considerations for those staying - because of its central location, the apartment can be a bit loud at night. It didn’t bother us, but know that others can be a little bit more sensitive to noise at night. Second item is that there are lots of stairs to climb (and no where particularly close to park to quickly take the bags in), so be aware when packing.
