This place really exceeded our expectations. I came with a group of three, and after having traveled with a much larger group, we were thrilled to have our own rooms with large beds!
Chiara was super quick and kind in her communications. We had an issue with a leaky sink in the kitchen and she sent someone over the next day to get it fixed and it wasn't an issue. We also fully enjoyed the Airbnb, with the cute little terrace for some morning coffee. The location of the place was also really great. We were close to a metro station (about a 10min leisurely walk), a few bus stops (5min) and really well situated amongst local restaurants and bars. It felt really local while still being a really walkable distance to Vatican City.
One of the bedrooms didn't have an armoire and only a hanging rack for clothes, while the other two bedrooms were a bit bigger with their own chests for clothes. It did get a bit chilly at night, but we found some extra duvets in the closet of the middle bedroom so grab those before you go to bed. The place was very clean, and while the kitchen was a bit small for more than one person to be in at once, it was more than sufficient to cook a good meal. If you're in the back two bedrooms, the windows are street facing and you can hear a little bit of street noise of folks passing by, but it's a pretty quiet street and we had no problems sleeping.
