The apartment is great, very central for the Old Town and really close to the Meadows, as well as being very close to the amenities in the Quartermile. It's a modern apartment, which means it was a lot warmer than any apartment I've stayed in in Edinburgh before, which was especially nice since I was visiting during the "Beast from the East" with a lot of snow and wind.
Kathy was wonderful, very responsive to messages and very keen to get everything sorted. Although the flat is managed, I got the impression that Kathy was a driving force behind getting things done, and any time I contacted her (for example to extend my stay when the trains were cancelled) I quickly got calls from the management company.
I would definitely recommend the apartment for anyone visiting Edinburgh.
