The apartment was in a wonderful location. Restaurants and transportation were a short walk, plus there were several sights, like Calton Hill that were right around the corner. Access to the Old Town is a very short walk over the North and Waverly Bridges. Bus and tour departures were nearby either on the Waverly bridge or right across the street. The airport bus departs from the Waverly Bridge (about a 3-4 block walk) every 10 minutes for about $5.
Apartment: Our apartment was clean and charming. A bit old, but that's part of the charm of Edinburgh. There were beautiful gardens around the building and a view of Calton Hill from the living room. The kitchen was reasonably well-equipped for our needs and included a washing machine - very handy. The bathroom had been updated to include a nice, large shower with plenty of hot water.
