Agie's place is very clean and the decor was amazing. We enjoyed our stay and would come back again when we go to Edinburgh. it's perfect for group of friends, family or 2 couples. Coffee and tea were available. There were seasonings as well if you want to cook something.
Distance wise it's about 10 minutes walk to princess street. About few minutes from York street tram stop if you will be coming from the airport.
I highly recommend this place for your stay in Edinburgh!
