Well, all has been already said from previous guests at athers lovely place: the room is spacious, modern, the seperate bathroom is clean and ather proved to have a nice hand in finding nice pictures and beautiful accessories to decorate his flat.
We stayed 4 nights at his place and had the flat most of the time for ourselves. He wasn't there for the checkin because he was traveling because of his job. A friend of his gave us a very friendly welcome though and showed us around the flat. Ather wasn't there the first three days, but he was always available via airbnb app and answered all our questions very fast.
On one side it was very cosy to have the flat for ourselves, but as he wasn' there in the beginning, we couldn't get tipps and tricks from a local first hand. But there's nice people on the street in edinburgh to ask
