Perfectly located room, right in the center of Edinburgh on one of the main streets. You can see Edinburgh Castle from the staircase. The room is small but adequate for a short stay. The bed is comfortable, albeit short, especially for taller people. The only downside was the cleanliness of the apartment.
Bee and Elina are very helpful and have lots of advice.
Overall, a great apartment at a good price, if you don't have high expectations.
