I recommend staying at Roberto and Giulia’s place - they are very nice and helpful people - check in was very smooth- Giulia showed me everything I needed to know including useful informations about city and public transport, place is a gated condominium with a private underground parking spot, neighborhood seems to be very safe as it is surrounded with embassies of different countries- apartment is well connected to the city center by public transport, and it’s also relatively close if you want to go to a concert at Stadio Olimpico, there is also a supermarket 5 minutes away,
Overall nice experience in Rome.
