Someone was waiting for us on arrival and the young lady was extremely helpful and friendly. She showed us where everything was and even lent us her own map of Edinburgh. The flat is as described - right under the castle - amazing! There is a window seat too, so you can admire the view of both the castle and Grassmarket at your leisure. We loved Grassmarket. There was always something happening, even a parade complete with pipe and brass bands one day! It wasn't noisy at night though and we slept very well in the extremely comfortable bed. The apartment was very well equipped, even some pantry items to help us with the basics, which we hadn't expected, but which was very welcome. When we struck a small problem in the kitchen we were talking to someone on the phone immediately and two other people came to the door within minutes - truly amazing service. All in all we had a wonderful week in Edinburgh, improved (if that's possible!) by our apartment. We will certainly highly recommend the apartment, Aileen and her tea, and would love to return ourselves one day.
