Claudio is probably the best host one can get. His assistance began even before we arrived to Rome. Thus, he had explained the ways to get from the airport to his place and even provided a timetable when I chose to come by bus. He also emailed several links advising to make early bookings in museums. In the apartment there are a lot of information to help a visitor - about nearest shops, transport tickets, as well as a number of maps. Claudio himself is very hospitable, pleasant and responsive, ready to help with any problem.
The apartment is very convenient, has several pieces of antique furniture that makes it feel quite authentic given that you live close to Vatican. At the same time, bed, bath, kitchen are modern and comfortable.
