The apartment is great, really clean and tastefully decorated.
On the other hand, the location was a bit far from the center of Edinburg, it is connected by bus but it is something to consider. I would also like to mention that the beds of the second room are really small (I guess 80cm). If you are traveling with kids they would be okey but for adults they are too small. None of the mattress are good, they are all quite uncomfortable.
The arrival was great, they help with everything. Mary answer quickly and has a document prepared explaining everything you should know about your stay.
There is a Tesco Superstore really close to the apartment which is great.
