We had a great stay at Karen's place. There were a few small hiccups with our stay but they were handled quickly - namely that the set of keys left for us did not fit well in the front door and we had to call the host to let us in. The stairs were also quite difficult to navigate with large heavy suitcases so do take that in mind! However, the apartment was absolutely gorgeous and had an amazing view out of the kitchen window. The location can't be beat as it's right on the Royal Mile and easy to get around to various shops, pubs, and attractions.
