Caroline’s place is in an excellent location being walking distance to the major sites of Edinburgh. It is next door to Fringe venues, which we made use of. There was some late night noise but earplugs worked fine.
The downstairs bed was a bit firm, the upstairs bed very soft/lumpy and this room really does just fit the bed. The upstairs bathroom also very compact.
We were two couples, any negatives were outweighed by the positives.
