Excellent located apartment. The communal entrance to the flat is filthy and feels unsafe but once you step into the flat you forget about it. The flat is a huge size for the number of people it sleeps. Only issue is the there is one bathroom and no separate toilet for the whole flat (which sleeps 12 people) so mornings are a little difficult.
Also the fact that you have to walk 10 minutes to pick up and collect the keys is a little frustrating but was a smooth process.
Overall the flat was warm and welcoming. Excellent value for money for a big group that just need somewhere comfortable to sleep whilst exploring the centre of Edinburgh.
