I loved staying at Constanza's air bnb. The room was nicely decorated and comfortable. Loved having the terrace and the AC worked just fine for me at night. The location is perfect --a 10 minute walk from Termini, down the street from major bus stops, and walkable to Trevi and the Colosseum. The air bnb was surprisingly quiet and the street seemed pretty safe. It was on the top floor, however there was an elevator so there were no issues. Costanza was easy to communicate with and went above and beyond with recommendations. I would definitely stay here again.
