I didn't meet Jazz/Silvia, but their property manager, Mel, was the absolute kindest and friendliest airBnB host I've had. She waited late for me after getting lost on arrival, and was sweet enough to let me store my bags in her own apartment lot because it was closer to the station. If you're ever in Edimburgh, I'd highly recommend staying here :) location was prime, right next to main areas and Arthur's seat!
