Olive's place is terrific! While we didn't meet her, she provided all the information we needed for check-in and check-out before arriving.
The location, which you can see from the pictures, is perfect. The living room and kitchen look out on Edinburgh Castle. You're centrally located to many of the best/most popular places to visit in the city.
My wife and I thought the bed was very comfortable and enjoyed relaxing in the living room in the evening. We would definitely return here for a future visit to Edinburgh.
