Fantastic location, stylish and a great place.
Me and my parents (both seniors) were able to visit all main attractions walking from the flat. They loved the LPs player and the convenience of having plenty of restaurants options near by.
The flat is on a 1st floor so street noise can carry. However, it is on a quiet street (in the old town centre) and other than the ocasional walking group of people, noise is not a challenge.
I would certainty recommend the flat and looking forward to go back and keep on exploring Edinburgh.
