Rosanna's son Francesco was very welcoming and made check in simple and easy. Note that they charge a hotel fee of $3 per person per night (cash). This rule is poorly regulated by Airbnb and was not mentioned in the listing, so it's hard to say if this is rule truly applies to their Airbnb business and/or is legal?
Their home is close to the Vatican and a good hearty walk to Roma's other tourist attractions (about 1.5-2 miles each way). Also close to San Pietro train station, metro lines and restaurants.
Breakfast consisted of simple yogurt, pastries and cakes and they were so sweet to pack us a to-go snack when we couldn't make the breakfast time.
The room itself is comfortable and has air conditioning which was nice to come back to after a long hot day out. In the room, they provide towels, water, teas and a hairdryer. They do a daily housekeeping as well.
Overall, no major complaints and their place worked out well for this first time Visitor to Roma.
