This was our best Airbnb experience. I've been Rome two times before this visit and for the first time, I prefer Airbnb to a Hotel. Monica's place has an extremely good location to visit Rome. I love that neighborhood. It is really at the center of the city and very near to Colosseum.
For Airbnb experience WYSIWYG (what you see is what you get) is very important and Monica's place is more than what you see. It's a comfortable (up to 5 people), clean, safe, warm place. Monica is a lovely person. You can ask her about anything and her response rate is very fast.
I (we) strongly recommend this place if you plan to visit Rome.
