A great and beautiful place to stay! I and my girlfriend stayed at this place for a week and celebrated a New Year. Alessandro did everything for us to keep our experience at the highest level. He met us on at the train station, then he took us, with his car, to his apartments. He also made a quick tour around local places advising us good restaurants with a tasty food. Also, he gave us a detailed guide about Rome and which places are best to visit, so he saved us a lot of time.
You should keep in mind that Alessandro lives in his private apartments, so you don't need to share a kitchen with him, so it feels like you live in your own apartments. There are two more rooms for rent, so you might live with other guests, but we had no problem with that at all.
Room was a bit cold in the winter, but Alessandro brought us an extra blanket, so we felt better.
All in all, I would definitely recomend staying at this place.
Thanks.
