The flat is perfectly located, in a nice area close to everything but not in the middle of the noise or chaos. We went during August festival which is very noisy and busy but we didn’t have any problem at all, we could listen the music form the show at the castle but was not uncomfortable. The view of the castle is perfect, and we got fist line view of the fire works. I would use it again as I believe the location is unbeatable. I loved Edinburgh.
