Fantastic location. A literal stone from the Pantheon. Marco was an excellent host, he received us, suggested some excellent places to experience the cuisine and even arranged a taxi for us, it took us 30 minutes from Ciampino. There are no metro stops nearby but it's excellent to walk everywhere. Also points to note for travellers is that there are no toiletries provided, but it was a non issue for us. Will definitely stay with Marco on our next visit.
