It's very conveniently located if you are looking to explore the old city. The apartment is just next door to the Vatican and is maintained in a perfcet condition. We were a family of six and were extermely happy with the stay.
Fabio is a great host who not only waited for us for an our as we got delayed on the way but he met us personally and explained everything about the apartment and answered all our queries on exploring the city. It's as professional an airbnb experience as one can get.
We really appreciated the small touches of hospitality like electric converter sockets, maps, books and a host of groceries. Its a big relief to find items like milk, juices and other groceries when you arrive at an apartment after a long journey. Would strongly recommend the apartment. Thanks Fabio
