Was a little dubious booking as there were at the time no reviews and the place seemed too good to be true, but it was perfect. Spacious rooms, great location, and lots of useful amenities which all worked well - 2 toilets, oven, TV etc. Only one of the bathrooms has a working shower, but that was perfectly fine. Strangely the Airbnb listing said there was no washing machine, but this is incorrect. We naver had any trouble with neighbours and in fact barely saw them. The curtains in the bedrooms weren't great at blocking out light in the morning, but I don't think any of our party struggled with this.
It's very close walking distance to a couple of supermarkets, and is right next to a bus stop giving the place great travel to Edinburgh City centre. It's probably worth remembering there's several streets in the area called 'Appin', as one of our lot got lost trying to find it.
There is only one copy of the keys, which we stored in the outside lockbox. When we wanted to get in, we had to unlock it, open the apartment door, then go outside again and lock the keys up again. This wasn't ideal especially at night, but was a very minor inconvenience.
I feel like this review has been quite harsh sounding, but we loved our stay and would absolutely recommend the place to anyone looking to stay in Edinburgh.
