Perfect place to stay! Safe, beautiful and historic zone. It is near the Castle, few minutes to Holyrood Palace and like 5 minutes to a market (Sainburry) where you can buy food to cook. Amazing place. Polite workers. You have a locker in the room. If your luggage is bigger than it you can put it in the luggage storage that is under video control. I recommend it and definitely will host in Castle Rock next time in Edinburgh.
