We stayed in this apartment on our girls' Christmas trip to Edinburgh and were very happy with the accommodations. The place is so much bigger than the pictures show, so we had ample space for the two of us. Beds are comfortable, the common areas nice and the architecture beautiful. The location is great, a 10 min walk to the Princes st and couple of minutes to the tram that takes you to the airport.
The weather was quite cold when we arrived, below zero centigrade, so the apartment was very chilly on arrival. Once we figured out the heating system and how to adjust it, the apartment warmed up relatively fast. Overall we had a great trip and were very happy with the apartment.
