What a great find!
My partner and I stayed for 3 nights with our two children (8yr and 12yr). We hired a car from the airport and drove to the apartment (about 20mins). Finding the apartment was super easy and we parked in the garage. The apartment is really spacious and both rooms are a great size. It's really quite and we all slept well. There is a tram stop just round the corner and lots of shops and cafes close by. I've stayed in lots of Airbnb's and this one is by far the best. We will definitely return the next time we're in Edinburgh.
