Giacomo is a warm and friendly host. I'd recommend his space for younger travellers who can tolerate some noise at night and some distance to walk to the center. The space is as shown in the pictures. It is your private room and was clean and quite big.
Giacomo was super helpful as he suggested many of the things I did and I could not have concluded a better visit to Rome without them!
He also speaks very well english and french besides his Italian. Very welcoming and hospitable. 5 stars for the experience.
