I had a really lovely stay here- the location is absolutely brilliant (especially during the Fringe), it was incredibly clean and had a really warm, homely feel to it.
The WIFI was also really speedy which I very much appreciated!
The only thing I would say is the fan extractor doesn't work, so every time I cooked in the oven the smoke alarm would go off, and also the hob was very slow to heat up and seemed very weak (nothing ever actually reached the boil), so it's something to consider in terms of what food you buy/how much you're depending on the cooking facilities. For me, having lots of food allergies, it meant it was slightly difficult to manage.
Other than that, I would definitely recommend, and Lisa McKinney was a very good host, responding very promptly and with clear instructions about check-in and keys etc.
