Great location, great apartment!
We really enjoyed our stay at this apartment right on the Royal Mile. Everything we wanted to see was in was walking distance and the trip from the airport was easy thanks to the host's detailed instructions. These also helped us find the apartment easily. We love places with a lockbox key making it so easy to check in and out.
The apartment was clean, stylish, and comfortable. The back room is indeed very quiet and we slept very well. The room facing the front had more night noise but it's high enough up that it wasn't disturbing to the member of our family who slept there.
There are handy extras in the apartment like soap and shampoo, plus instructions to the nearest supermarket which was all very handy. Highly recommended!
