Overall good accommodation in a great location with communicative hosts.
Pros:
The flat is centrally located which makes it very convenient to walk and visit Edinburgh. The bed was very comfortable (mattress and pillows) with very clean white linen and white towels.
There was a welcome basket for us upon arrival.
The kitchenette is well equipped with most of the things you need.
Cons:
The entrance to the building is outdated and smells damp but as I understand is under work and is not their responsibility as it is a common place.
There is also dampness in the flat, mostly noticeable in the hallway which was not a big issue as most of the time we were out and the bedroom was fine.
Our main issue was with parking. In description it says off street - paid, however the maximum is 4hours and we had to find a nearby parking where to leave the car for our stay and Christmas is busy period with many tourists in town. If we knew probably we would have re-consider the accommodation.
