Duncan's appartment was really comfortable; like pictures you can see on the site. We were 11 people, we had enough space for all of us. Flat is really spacious; just to mention there is not lift on the building but there wasn't a problem for us.
Location is not in the center but you can go by bus just in a few minutes.
You have a Tesco and Lidl supermarkets just in the corner, take away restaurants in the town.
Communication with Duncan was easy and he provided all information we required. Don't hesitate to contact him if you want to visit Edinburgh.
