Location (on the mound, literary right next to the castle) and the view (all over Princess Street, new town, and the harbor) are absolutely wonderful. Living room is comfortable; kitchen is basic. It's an old building, so do expect some dust. The apartment is on the sixth floor (hence the view) - so you do need to be comfortable with steps. It's about six minutes walking from the airport tram; eight minutes from Edinburgh Waverley train station; ten minutes to the Marks and Spencer grocery store. The building complex has its own wikipedia entry; expect to see folks taking pictures every time you leave the house. Owners are great hosts. Excellent communication.
