My wife and a friend of ours spent four nights in this spacious flat on the west side of Edinburgh Castle, about a half mile walk away (with quite a climb in elevation).
There was no "meet and greet" service provided, and the property uses another service besides Vrbo for most contact and other matters.
There are about 50 stairs from the street level to the living area, with no lift/elevator.
Beware that "self-catering" means there is no soap, detergent, shampoo, paper towels, etc.
Closest parking is just below the castle, about £40 per day. This section of Shandwick Place does not allow private cars, only buses and taxis.
The Sainsbury's store right next door is very nice and well stocked.
Although the flat is on a major street, it was very quiet.
We truly enjoyed Edinburgh and would definitely consider this place for a return visit.
