We are currently doing an Euro trip with my girlfriend, and we stayed at Harriet's place for our stay in Edinburgh.
This is by far the best Airbnb we had in our trip.
The apartment is very clean and well located, the room is big, and the neighborhood is calm and safe.
There is a bus stop 2 minutes walk from the apartment that will bring you pretty much wherever you want to go.
You can also walk to the city center (apprx. 15 minutes walk).
I would 100% recommend this place, as I will 100% book again for my next stay in Edinburgh!
