Kathleen's place is managed by an agency, which is well-organized and does a very good job at providing information and answering any questions.
The apartment is located on a quiet street, within walking distance to the touristic center, a couple of supermarkets, and several restaurants. It also has good bus connections.
Very clean, it also offered more toiletries than usual for an Airbnb.
It was great to stay there with my wife and daughter and we'd surely try to use it again if back in Edinburgh.
