First of all, Simone is an extremely attentive host. Despite a small disaster causing me to be several hours late on a rainy Sunday evening, he was at the apartment to greet me and show me around. He checked in on me during my stay and arranged fabulous transport for me to FCO on my departure.
The studio is perfect...cute, comfy & well appointed, plus very quiet despite its incredible central location, from which you can walk nearly everywhere you might want to go in Rome. If not, you're quite close to many of the key bus routes.
I'll definitely be back!
