If its location you're looking for, this place is AMAZING. Its a 2 minute walk from Edinburgh Castle, its on the Royal Mile. You couldn't get a better located flat. However, I would only recommend it to a group of 22 year olds who are just looking for somewhere to lay their heads after a night drinking.
The place needs a proper clean, especially the kitchen area.
The bedrooms need to be aired, probably doesn't help that some of the bedrooms have no windows, or possibly windows that look out onto a wall. The linen on the bed is straight out of Soviet Russia and the beds weren't made - the duvets were hastily pulled up over the pillows but that was it.
The second shower didn't work for 2 days. I didn't even try contacting the owner as her email said that she was a bit of a distance away in an area with limited wifi - convenient!
I think when you're paying a lot of money for a place like this, you expect a little bit more than just "location"
