Without doubt this has been so far my best experience with airbnb.
Marii is super friendly and kind. She provided information for arriving more easily from the airport. When we arrived she offered some antipasti and she was always very communicative. The room itself is very good, has its own bathroom with all the amenities, the bed is comfortable and the view is very nice. The room has a coffee machine (Nespresso like), there is also tea, biscuits and other treats provided :) . There is a small fridge outside of the room which we were able to use and, moreover, she provided some snacks (yogurt, juice etc) and also offered to cook some pasta. The place is very well located if you want to move between the Vatican and other touristic places.
I highly recommend this place.
