My wife and I stayed at Matilde's place for two nights. It was very nice. The room is cozy and elegantly decorated, the building is very nice with an amazing inner courtyard.
It was very calm and quiet, which feels especially great after the chaos of Rome's center.
Matilde was an amazing host. She was very responsive and accommodating and made the whole process very easy and smooth. She also gave us great recommendations for hidden gems to visit.
I can only recommend staying at her Airbnb!
