I will highly recommend La Torretta. If you want to do a day trip to Milan central, just leave your car ar the hotel, walk to the street behind the hotel, catch the bus to the station, and get the train to central stations (duomo, etc). It takes less than an hour, hassle free, parking free. Dont park your car around the stations near the hotel, I read a lot of break-ins. Just leave at the hotel and catch the bus.
Spacious parking, clean rooms and bathrooms, friendly staff. Relatively new building.
