My boyfriend and I stayed in Cinzia's apartment for one night in June. Cinzia was there to welcome us when we arrived, and was friendly and helpful and even left us homemade cake!
The apartment itself is very stylish, and a nice compact size for one or two travellers on a city break. The bed was very comfortable, and everything was spotlessly clean. As an added bonus, there is a lovely big balcony with flowers and a view over the city.
I would definitely recommend staying at Cinzia's apartment for those looking for a base to explore Milan!
