Marzio's place is great, nice as described, at a well-situated location (just under the Citta' Alta). There is a supermarket (Carrefour Market) near the apartment, about 10-15 minutes walking on a greenway or by the street (2-3 minutes by car).
Marzio has been very helpful by giving some good tips, and by providing quickly some missing items in the apartment.
It has already been said on previous comments, the street (Via Baioni) is a main street and the rooms overlook it, so it's quite noisy. But it was no big deal for us.
Also, be careful if you rent a car, the parking box is very small, so I'd suggest to stick to a small car. It's even better if you drive along the lakes, some of the roads are very tight. We rent a Ford Focus and I'd suggest not to take a bigger car.
