We had a lovely stay at Marzia appartment. The location was very convenient and Marzia and Massimo were extremely available for our arrival.
The appartment is small but fonctionnal, perfect for a few days trip to discover the city. The building was quiet but the street is really noisy (lots of ambulances due to the hospital just across the street), but you are in the center of a big city so you cant expect perfect quietness.
One small precision : breakfast is not really included, only hot beverages are available.
