The flat is in a good location to easily get to central Edinburgh, but is not really suitable for more than 6 people, unless you don't mind sharing a sofa bed and there is only one toilet.
The front door opens right onto the street, which is very busy and you get traffic and passers by all night long, so it is difficult to sleep - especially in the downstairs bedroom, which also had no curtains.
OK for one or 2 nights max. A bit pricey for what it is.
