Stayed at Carol's apartment for 2 nights whilst in Edinburgh for the half marathon. The flat is in a great location- very central which enabled us to walk everywhere (including the train station) and has some nice pubs, restaurants and a small Tesco close by. The flat is well equipped and we were able to cook a couple of meals with no problems. Carol has been really easy to communicate with and the check in process was easy.
We stayed over a Saturday night and with the central location comes a certain level of noise overnight- but I think this is to be expected given the location and it was not a massive problem.
