I enjoyed my stay here. The place was clean and affordable, and Stefania was friendly and easy to reach. There are a few bedrooms in total, so you will share common areas (living room, dining room, hallways) with others. But I had my own bathroom, which was good enough for me.
The area is very safe and so close (5 min walk) to the Colosseum (surreal to go for a run around it). The area is a little touristy, however. Luckily, the Monti neighborhood is nearby (10 min. walk), which is a fun area with lots of cool restaurants and bars. Overall, a great place for a solo traveler.
