Giulia’s place is a perfect spot for a solo traveler or a couple. The apartment was clean & comfortable with good WIFI access & a washing machine in the apartment. The living room looks out on the square but the bedroom faces the interior of the building so it’s quiet at night.
Testaccio is a great neighborhood. It’s about 20 minutes outside the center so it’s less touristy more residential. Public transportation is readily accessible but I ended up walking a lot because that’s how I like seeing the city. Lots of great restaurants and food options including a local market worth checking out.
