I stayed here for two nights during a short stop over in Edinburgh. For someone who only had a bit of time to explore, the location was perfect. Smack in the middle of Old Town (a stone's throw from the Royal Mile on High Street), yet some how tucked away enough that noise was gone once you're in the apartment. In all the cities I have traveled to, I've never been so close to a major downtown street and still had it quiet at night.
The apartment is small, but perfect for 1-2 people. You honestly don't need much more space, and it has the basic amenities you'll need. Will was also super helpful in sending the easiest walking directions to the apartment (no way I would have been successful without them!).
