My friends and I stayed in Maurizio's apartment for a month during our trip to Rome. The location is perfect – Vatican City is within 5 minutes walk, and the city center is within 30 minutes walk. There are also several bus stops nearby. We loved getting coffee in the nearby cafes in the mornings.
The apartment is spacious, clean, cozy, and has a beautiful design. The kitchen is fully equipped. There were four of us, so having two bathrooms was also very convenient. Some days we didn't even want to go out because we liked being inside Maurizio's home :)
Maurizio as a host is extremely friendly, welcoming, and responsive! We had several small requests during our stay, and he almost instantly fulfilled them.
I very much recommend staying in Maurizio's apartment in Rome!
