A lot of things to say here. The flat is really well placed, even if Edinburgh is a relatively small city. The old town is easily reachable within a 30mn walk.
The neighborhood is nice, except within the building : we got woken up 2 nights by drunken neighbors, and the walls are cigarette paper thins. The commons of the buildings smells tobaccos and sometime cannabis. The building seems to be the least clean of the street, but still, the environment is nice, with a lovely multicultural population.
On the flat now : the renovated parts are corrects, the bed is a super nice king size, but the 2 extra beds are old and not really confortable. The heater in the bedroom can be noisy.
Overall, we got what we paid for, but it was not such a nice experience.
