Really great place and really amazing host! Paola made me feel at home and as a lone traveler that was a nice touch. She gave me some of her homemade tiramisu and also gave me some fresh watermelon. She was very easy to communicate with and was always very responsive. If you need anything, you can bet that she'll help you out.
The location is great - walkable from Termini. There is also an amazing gelato shop (Fatamorgana I think it's called) just two blocks down from Paola's apartment, and other restaurants in a couple blocks distance from here. The location is also residential and I felt very safe walking around. There's also a drinking fountain around the corner so that was a lot of fun.
FYI the beds are in a lofted area and you don't get a bathroom attached to your room, but there is a great terrace and I really enjoyed my stay here.
