I recommend it 100%.
Gabriele was a very nice, available and accommodating host. After arriving 3 hours later than scheduled because of our flight delay, he proposed to come picking us up at the train station quite late on a Friday evening and drove us back to the train station quite early on a Saturday morning.
The apartment is very confortable, fully furnished with towels for everyone and other things very appreciable when you arrive late, early, or during the week-end. We were 3 but it can easily fit 4 people. It is well-located, about 10 min walk from the metro and bus stop, a mini-market 2 min walk, the train station about 15-20 min walk. The only snag could be that it is a bit noisy at night (italian ambulances are terrible !) but after walking all day, trust me you finally fall asleep.
Recommended 100% !
