Great location, very close to most of the sights in Edinburgh. The host was very helpful and accommodating despite our early arrival time.
Some things to note: you can hear the footsteps from upstairs, and the plumbing in the building seems a bit old so the toilet does not flush so well. Also, the flat had recently sustained water damage so if you're particularly sensitive to dampness and are going to be at this place soon, do check if it's been cleared up.
