The flat is in a fantastic, central location and was very reasonably priced. It also looks exactly like the pictures so no unpleasant surprises.
Check-in was fine, if a little faffy as compared to a key-safe, but instructions were clearly communicated to us before arrival so I can't complain.
Rebecca was very responsive with communication in general. She also sent local area advice prior to arrival; I've lived in Edinburgh before so didn't necessarily need it but it looked to be very helpful for someone new to the city.
I wouldn't hesitate to stay here again or to recommend it to a friend.
