Do yourself a favor and stay at Sergio's. I can't say enough about Sergio, he made me feel so comfortable and welcome and instantly answered all messages and is willing to answer any questions about the apartment or Italy in general. Best host I've ever had (listen to his recommendations). The apartment is very cute, clean and very modern style, with every amenity I can think of. The apartment is in a cool neighborhood full of great restaurants and friendly people everywhere and is very close to all the public transit you need.
