I stayed in Vroni's flat for two weeks in December while I was doing research at the National Archives and National Library of Scotland. Vroni was very welcoming and laid-back and really made me feel at home with her family. She really knows the city and it happy to share knowledge on where to go and what to do in this fabulous city (and where to avoid the tourists). The flat is warm and comfortable and the room itself incredibly spacious. I found the location itself to be perfect for a short walk to all the sights in Old Town and New Town; there are also tons of good pubs, restaurants, and movie theaters within minutes off Lothian Road. I don't think you'll find better value on Airbnb for that location in Edinburgh—and great hospitality, to boot!
