First of all, Chiara is by far the most friendly, enthusiastic and communicative Airbnb host we have ever had. We didn't even meet in person but I'm pretty sure we're best friends now.
Her apartment is perfect. It has everything you'll ever need, you'll be incredibly comfortable, and the elevator is a huge plus. Great bed, good internet, beautiful bathroom.
You'll love coming 'home' to Trastavere - it was bustling outside in the evenings even in the cooler nights of late October. The apartment itself is on a quiet street (which to me is a good thing!) but the bars and restaurants are just steps away. Another plus on the location was getting to and from FCO via car service was really convenient. We would 100% return to Chiara's place!
