My partner and I had a great stay at David's place.
We were in town for a nearby wedding so for us the location in central Edinburgh was key.
It's very close to the tramline, so you do hear trams going past from time to time when in the beautifully styled and appointed livingroom/kitchen space, but this isn't a problem from the bedroom at the back of the property.
Reviews of the outstanding cleanliness are true - the entry corridors and rooms of the flat are immaculate!
We did have to was a few bits of cutlery and glasses, but that's a small price to pay on the whole.
As for David himself, we didn't meet, but all interactions through air bnb were quick, polite and easy.
I'd definitely recommend David's place to anyone looking to stay for a few nights in central Edinburgh!
