Maria's place is beautifully decorated, very clean and is well stocked with everything you need for a comfortable stay. It is in a fantastic location, even if you don't want to eat or drink late, it's nice to people-watch from the apartment balcony, or stroll around in the evening. Also there is an excellent vegan restaurant, called Panghea, less than two minutes away, around the corner (right as you come out of the door). It's a set menu as it's small but good value for money, and finding a vegetarian restaurant isn't easy in Italy!
Even though the apartment is on the canal, you can't hear the noise from outside as long as you have the windows closed. The Aircon is quite noisy so that may mask some but you can sleep with the Aircon noise.
There is a supermarket about ten mins away, and the metro (M2 at Porta Genoa) is only five minutes away and you can travel into Milan easily.
We would highly recommend Maria's place.
