Giorgia's apartment is located near the Vatican so the museums, St. Peter's Basilice etc. are all within walking distance which was great! There are several bus and metro stations near the apartment too (Ottaviano/Cipro) so you could easily reach the other sights (you can buy 24h/48h/72h tickets at the stations or at little supermarket shops - we prefered to get it in the stations). Giorgia was very responsive and kind - she helped us by contacting the landlord when a resident of the building the Airbnb is in insulted us on the first morning via telephone because we arrived late the evening before and may have made some noise unpacking our luggage... Beware that the residents take their resting time from 22pm to 8am + 2pm to 4pm VERY seriously (they threaten to call the police if you're too loud - so we didn't even dare to shower before 8am).
The check-in process after 9pm was a little exhausting since we had to walk up a hill to a 24h flower shop to get the keys but we were thankful that Giorgia made a late check-in possible.
The apartment is pretty well equipped - we only missed some dishrags for kitchen but cooking utensils, a big fridge with freezer compartments etc. are all there. There's also a supermarket reachable within a few minutes (which closes at 9pm) and another one which is open 24h (around 10 minutes).
Some things the host is not at fault for but we faced during our stay:
We were six people with two couples and two pretty tall guys who planned to sleep on the sofa since the double beds were taken by the couples but the sofa is a little too small and shaky for two very tall guys so they had to get by with two mattresses - next time we will probably look for an apartment with 6 beds.
Furthermore, it's very loud on the streets at night which made it impossible (at least for me) to sleep with the windows open. The rooms have air conditioning to regulate the temperature but some fresh air at night would have been great.
All in all, a good stay!
