Myself and my girlfriend stayed here for four nights.
As described it was right across the road from a tram stop so it was incredibly easy to get from the Airport to the accommodation. Likewise, it's situated about 20 minutes walk from the old part of Edinburgh, so it's easy to get about without a car.
The room itself was incredibly modern and clean, in comparison to the shell of the building which is rather old. As a result, we think the windows of the bedroom might be single pain as the room is incredibly loud at night as it looks out over a main street. Now, one can wear ear plugs but if you feel uncomfortable doing so, as I do it is rather difficult to have a restless sleep.
So, overall it is a good spot and definitely worth the cost but do be prepared to have a restless night or two.
