I have used air bnb a lot around the world and I have to say this was one of my top stays.
My girlfriend and I stayed at Katrina's for 9 nights - excellent location, amazing property, Katrina was such a good host - leaving food items for us in the kitchen and giving us all the information we required.
Check in was a breeze - my flight landed into Edinburgh late morning and Katrina left the keys in a key lock and gave me the code.
I would highly recommend staying here and when I return to Edinburgh I will be for sure checking to see if there is availability here.
