We spent 3 nights in Rome and for the entire time we were praising our Airbnb! Tiziano was super nice and welcomed us upon arrival.
The room and its private bathroom are simple and extremely clean. As there is no private or shared kitchen, you can't cook or conveniently store food, in my opinion the only disadvantage of the place.
The best part was definitely the location: just across Castel Sant'Angelo, over the river. After walking the entire day, it was very convenient to go back to the airbnb, grab a jacket and go out again for dinner, no need for public transportation or long detours.
We want to visit Rome again, and we'll probably stay with Tiziano once more!
