I had a great experience in David's apartment. The location could not have been better and afforded us every opportunity to see all the sights that Edinburgh has to offer. You will be able to walk literally any where you would like to go in the city.
The only downside at all is lugging your suitcase up the long spiral staircase to the apartment but other than that I had no complaints.
Additionally, David was very helpful and always quick to respond with helpful information. I definitely recommend staying here.
