Ingrid is great! She is the most organized airbnb host: when I arrived she handed me a booklet with wifi details, restaurant and other recommendations. She also handed me a map and marked out all the must see places, with best routes, secret tips to avoid lines etc.
The room is great. Better than the pics. The noise (which is just people talking from down the street) didn't bother me at all - if you have spent your day well in Rome you should go right off to sleep in the super comfortable bed. I would definitely recommend this place and like to stay here during my next visit to Rome!
