Georgia was a very attentive host, promptly answering any questions I had before arrival, letting me know she would be a few minutes late to check-in, and dealing promptly with a minor issue I had during my stay.
Her flat was exactly as described and exactly what I needed during my Edinburgh Festival stay - a very comfortable (and quiet) place to stay and within walking distance of all the venues I visited. But frequent buses are also available if you're not so keen on walking.
I wouldn't hesitate to recommend this flat for your Edinburgh stay.
