Massimo was readily available through whatsapp despite him being out of the country when we were there. His place is a short walk from the metro stop, and a short commute to many of the major tourist attractions! The apartment itself was really spacious and clean, and there are 2 bathrooms so you wouldn't have to worry about long waits when the place is full with other guests. It was a great stay and I would definitely recommend!
PS there's a great cannoli place near the metro station! :)
