Carla and Massimiliano's place is a comfortable, clean, cozy and well lit apartment. The bathroom is quite big for european standards, and it has a good kitchen. Great for eating in if you want to cook and have a break, there is a little balcony where you can watch the evening sky as well. The house was already stocked with some bites and drinks as soon as we got in :)
The place is very close to a Tram line that can take you a lot of places, and it's a good enjoyable walk from the apartment to the Duomo and city centre. There are plenty of good restaurant options (really good, not touristy) around walking distance.
Massimiliano is very kind! - he lives in the same building so whenever we had any questions he was there and happy to help. Would definitely recommend, perfect place for a couple!
