Apartment was perfect for what we needed for our weekend stay in Edinburgh. In the heart of Old Town and a short walk to the castle. It is right on the Royal Mile.
Fidelia was excellent in her communication and response time for a couple of questions upon check-in.
As others have mentioned, the apartment is up three flights of steps and there can be a good amount of street noise, but that is to be expected if staying in a popular downtown area.
I would highly recommend this apartment for a visit if you want to stay in Old Town Edinburgh!
