I found this place a little last minute - given that, and the high prices in Edinburgh, it was okay for the money. It is, as advertised, a basic flat but a couple things made it a little less than what I'd expect. There was a full kitchen bin on arrival, food remnants in the sink and the shower was a little dirty. Also, someone did mentioned this previously, but the sofa is broken and slants forward, so not the most comfortable. The bed was big and quiet, but as someone did mention previously the mattress is very thin. So it was fine for a couple days, but personally I couldn't have managed long-term.
Overall, mostly as expected, and the only available place last minute that wasn't insanely expensive, so it worked out fine.
To end positively, the location is fabulous and it was very quiet.
