I tremendously enjoying staying at Andy's place! Check-in was smooth and speedy, which I appreciated so I could go out and explore as soon as possible. The apartment was extremely clean. The shower was great, both for water pressure and temperature. The bed was extremely comfortable. The apartment is about a 20-25 minute walk from Grassmarket (center of Old City where the castle is). This was fine for me since the weather was beautiful while I was there, but it is something to consider if direct proximity to all the attractions is priority. Overall, I definitely recommend staying at Andy's apartment!
