The apartment was actually better than described. The pictures on airbnb do not do it justice. It was clean, no odd smells or stains, very well equiped. Our host, Cristobal, was very nice and communicative, answered all our questions and even waited for us at the apartment so we could check in early. The apartment is very, very close to the Vatican (yes, you can see St. Peter's dome right from the window), close to the subway, shops and restaurants and the neighbourhood seems to be very quiet and safe. It's also very well connected with the tram and bus lines (even those coming from the airports). All in all we had a great time and I highly reccomend this apartment and this particular host. Thank you Cristobal!
