This place was as advertised. It was quite centrally located, easy to get to, and worth what we paid for it. It was no-frills, the bedding was minimal (no top sheet) and the pillows were pretty lumpy, but for a place to lay your head at night, it totally worked. Beware that the drunk people walking around at night are quite easy to hear. I was able to sleep ok, even with hearing them, but if you are a light sleeper this spot may not be for you.
All in all, we had a good time and were glad to be so close to all the attractions for the couple of days we were in Edinburgh.
