Federico was a superb host: frequent check-ins before arrival, arranged pickup to/from the airports (note his drivers only cost two Euro more for this service than the official white taxi flat rates to/from FCO, so it's quite a bargain considering the door-to-door service), he was there to greet us when we arrived and gave us a tour of the apartment and its appliances and showed us how things worked, as well as giving us valuable tips about places to go in the neighborhood to help us get acclimated quickly. Since we were staying two weeks, he also brought us a change of sheets and towels. Federico is a genuinely pleasant person and was super responsive to email/text/Airbnb messaging during our stay. Bonus points for leaving us a bottle of sparkling wine in the fridge, class act! He also

The apartment itself is in a perfect location (5-30 minutes walking distance from pretty much every major sight, plus you're in a great proximity to Trastevere and Campo di Fiori area, two great neighboring areas), and in great condition that is consistent with the pictures and descriptions shown on Airbnb.

The apartment, as it is in the historic center of town (centro storico), is in a very old building and the apartment itself is quite old, but has been updated with modern amenities and a comfortable bed. As we arrived in the wintertime (around New Year's), it was quite cold in the apartment, but the two wall mounted air conditioning units provided ample heat once things got warmed up and the space retains the warmth you build up (all windows are double-paned glass, so it is quite well insulated). Federico also brought us an additional space heater without us even asking; he is so attentive that I think he could tell we were in need of a little extra warmth.

We were very happy with the size of the apartment for two adults, though I would not recommend staying with more than that; there is couch in the living room that folds out to a bed, so you could potentially have up to four people staying here, but it might be a bit crowded feeling. It could be done, especially if you're spending most of your time exploring and enjoying Rome and just going back to the apartment to sleep. In my opinion, though, this apartment is best suited for a couple traveling without children, as were my wife and I.

It should also be noted this apartment is very quiet, which is a little suprising given how central it is. Since it's an old building, you get some creaking and "old house sounds" (e.g., radiator pipes knocking and moving water around in the winter to the neighbors), but the building only has I believe 4 units in it, and you don't really hear the upstairs neighbors much at all (there is another apartment directly above you).

Long story short: 10/10, would stay again, would recommend highly to friends and family.
