The flat is very fancy and super cozy. It has everything You could possibly need. Garbatella Metro Station is super close (especially for Rome) and the area is super nice and actually really close to the center, by Metro it takes 15 Minutes to get to Termini.
The communication was very easy and there is a board in the flat with restaurants, sights etc. that Flavia would suggest. i can highly recommend to stay there.
Ohhh and the terrace is excellent. It even has a roof and You can chill outside when it's raining. It's really big and You are completely alone, because You're in the top floor. Perfect Airbnb!
