Can't really fault this hotel.. £40 a night in Central Edinburgh! Everything is within 10/15 minute walking distance (Princes Street, Edinburgh Castle etc)
The staff there are really friendly and helpful
The only criticism I would say though is that the showers are a wee bit on the small side. I'm 6'3 and well the shower is a small square (I didn't have much arm room) you get more arm room on a train. However saying that, it's still manageable and I would definitely go back there again when I (eventually) visit Edinburgh
