The space is nice, there are two bedrooms and one small pull out couch which was broken and there were no linens for it anyway. My daughters would have liked to sleep separately, and were looking forward to having their own space.
The garage is tricky and tight, but excellent if you can manage it. There are huge main car doors going into the courtyard then a locked door under the building for the garage. We wandered around and asked a very nice man in the parking area who helped us. We had trouble with the fob, eventually got it to work.
Great location at the Palace end of the Royal Mile There is a shortcut to get to the Royal Mile if you go up the stairs in back to Lockend Close, brings you right out by Starbucks, two minute walk).
Definitely do the Mercat ghost tour if you can, it was excellent!
