Fantastic place, in a superb location; literally minutes from historical sites (Edinburgh Castle, Royal Mile etc), 15 minute + scenic walk to Princes Street and the gardens, plus the Grassmarket area itself is full of traditional and historic pubs! And a great area for Harry Potter nuts too! Ann's apartment is really nice and she was super helpful and provided some nice touches including an early check-in. Be sure to say hello to Greyfriars Bobby in the bathroom!
