We were in Massimo's apartment during our honey moon and it was great. The apartment is super comfortable and is very nice, it is better than the pictures!! It is also very well located near the Basilica of San Giovanni where there is a Metro station in the same line of Vatican City, piazza de Spagna, Fontana di Trevi as well as Termini train station.
Massimo was a great host!! He received us when we arrived and explained everything about the neighborhood, the metro station, the supermarket, the bus stops and gave us recommendations about restaurants which were great.
Don't hesitate in choosing Massimo's apartment for your trip to Rome!! Is a great option!!
