This was probably the best Airbnb experience I've had. Carol has a lovely home and it's in a beautiful part of Edinburgh with a bus stop right outside that takes you straight through the New Town and over into the Old Town. I couldn't recommend it more highly.
If you are bringing a car that there isn't parking on site. There is free on street parking evening to til morning and all weekend but if you plan to park up during the daytime during the week then you'll need to walk 8-10 minutes back from the free parking that's north of Ferry Road.
