Definitely one of the bigger Airbnbs in Italy. This was the last leg of our trip and it was the perfect place. Stayed there with my boyfriend and parents , and it was still super spacious.
We used Ubers and taxis to get to and from the main train station and airport. The fares were reasonable ($25-48).
The washing machine was a nice touch as we packed light for our 10 day trip. The place is also conveniently located across the street from a 24/7 grocery store and surrounded by small coffee shops.
As for getting around the city, we walked everywhere. Vatican city was only 10-15 min walk. Colosseum was 45-50 min walk. Trevi Fountain and Spanish Steps were ~40min walk.
The check in was easy and the host was super friendly.
Oh, and they have an elevator that we used for our luggage! Nice treat after the many many steps/stairs we climbed throughout our trip.
