The house it's really clean and well maintained, the bed is comfortable and the place is quiet during the night. As a bonus they even let us use a Netflix subscription on a big screen in the living room.
The only issue we found its with the neighborhood. Even if the house it's easily reachable using the public transportation we found a lot of homeless people on the bus, most of them high or drunk.
Fortunately Uber it is really cheap and the house it's close to center so with just 5£ in a 5 min ride you'll be right in the center of the old Edinburgh.
