Roberta is a friendly and thoughtful host.
She guided me around the apartment and gave me a great and recommended handbook with local tips. There's a great great great restaurant less than 100m from her place on the same street that was my favorite from my stay in Rome.
There's two bikes that I didn't get to enjoy because the city can be cold in January but if you come here in the summer, they come super handy and they are foldable so you can take them in the public transport if you need to.
