Three words... Location, location, location. The suite itself is very nice; there are high ceilings, washer/dryer, smart TVs in the living and bedroom, comfy bed, espresso maker, gas range, and nice and new electronics (a better iron and hairdryer than I have at home!). And the check-in was one of the best Airbnb experiences I have ever had. We were greeted by the hosts' friend Raoni, who showed us around the apartment, then gave us a map of Rome and some great recommendations and tips. He was an excellent advisor, and I felt confident he would be able to help us if we had needed anything throughout our stay. And, the hosts gave us a bottle of prosecco to celebrate our honeymoon!
But above all, the apartment is in the heart of Trastevere, a stone's throw from some of the best restaurants and bars in Rome. It can get a little noisy at night, and we were only there on weeknights, so I can't imagine what the weekend is like. It wasn't cacophonous by any means, and I think the sound level is a matter of luck with who is staying in the other flats in the building and what is going on with the nearby universities. Well worth the risk if you enjoy nightlife and excellent cuisine.
