This is one of the best places I have stayed so far during my five week U.K. trip. The view is incredible as when you look out the window, Edinburgh Castle is right above you. You are just a few minutes walk from the castle and the Royal Mile and other locations of interest. I started the day off at Edinburgh Castle, then walked the Royal Mile, went to Calton Hill and hiked to the top of Arthur's Seat all before 7pm. lol. There are buses that stop on Grassmarket or nearby so if you walk as much as I did in that one day and just don't want to walk another step, you can always catch a bus back to the apartment. Grassmarket itself has plenty of pubs, restaurants, and shops so you don't have to go far from the apartment to meet your needs. I will definitely stay here again if I am ever back in Edinburgh.
