We could recommend the place for three main reasons.
Location: Right in the heart of the historic city, you're easily within walking distance to main sights and points of interests (restaurants etc.). It's easy to reach from airport by bus (get Alibus to Porto di Massa and take a short walk). There are a couple of handy metro stations nearby (Universita, Dante...) for the times when you want to commute a bit further.
Terrace: A large terrace is facing a small quiet back street which makes it a nice quiet "chill spot" in the middle of a bustling city. A perfect spot to unwind at the end of the day or recharge in the middle of it ;)
Federica: Our host was very friendly and attentive. She is genuinely interested in her guests and provided us with plenty of great local tips which were tailored to our interests and needs. She came across as a very friendly and candid person.
