For tourist visiting Edinburgh, this is the most central place to be. Plenty of pubs, cafes and restaurants around. Most tourist sites are within distance. Edinburgh castle is within a straight 15 minutes leisure walk.
In general, the apartment is quite compact, clean and a well furnished kitchen.
The shower room is really small even for folks of small built. It is about the size of an aircraft toilet :).
Folks with heavy luggage beware...there are a number of steep steps to overcome as the apartment is on the 2nd floor of an old building. Otherwise, this a central value-for-£ airbnb unit.
