Antonio greeted us when we arrived, and was very friendly and helpful, helping me find out how to get to the Mercato Testaccio. Beds were extremely comfy, definitely equivalent to a bed in a hotel! Location wise, it's definitely convenient as it's just opposite the Termini station, but probably not very safe as I noticed quite a few sketchy people loitering around while we were making our way to the AirBnB. My mom also got pickpocketed around the area as well, so be very vigilant in the area!
