I had a great experience at Casa Calpurnia - Claudia was extremely kind and helpful during my stay and even provided me with transport from Roma Termini, due to some lucky timing on my behalf. The apartment itself looks exactly like the pictures; it's quite beautiful and well laid out. Rome can be really hot and nasty so it was heavenly to get a place with not only the most comfortable bed in Italy, but a really powerful air conditioner. There's nothing that I would fault with my stay and I would be more than happy to rent this apartment in the future.
