I stayed here for a short mid-week trip to Edinburgh. The room had more than enough space for me with easy access to the main bathroom (which was clean and tidy). The apartment was in a central location, just next to the university and not too far of a walk from all the main attractions. Other reviews mention noise but I had no trouble sleeping (although I stayed here during the week so it may be noisier on the weekend).
The apartment had all the essential amenities for an enjoyable visit. I would definitely consider staying here the next time I am visiting Edinburgh :)
