Amazing location. If you want to be in old town Edinburgh, this apartment is right where you need to be. . . Steps to the Royal Mile, great restaurants and pubs as well as Waverly train station. . .
The only thing you should have on your radar is that you will need to climb 2 flights of stairs to get to the apartment. I think it is pretty standard for all the apartments in old town, but something to know if that might be a concern.
