This is a cute apartment in an unbeatable location on the Royal Mile. You are steps from lots of great restaurants and shopping, and a short walk to many museums and other things to do. Despite being near everything, the apartment is quiet. The bedroom is at the back and we never heard any noise at night. Check-in was a breeze; we were sent clear and helpful instructions (with pictures!).
A couple of things you might want to know:
The apartment is in a charming old building. As is common in older buildings, there is no elevator. It is necessary to walk up two flights of stairs, one of which is outside and a bit steep.
There was internet access, but it was unreliable, kind of on-again off-again throughout our week-long stay.
