The house is big enough for 4 persons, close to the metro station, with access to the city center (only 3 stations), to central train station (7 stations), the Cadorna train station (6 station, changing at Duomo) if you want to go to Lake Como. Also, you have a great restaurant for dinner or lunch just outside the apartment and a Carrefour Express at 6 minutes of walking. The area is quiet and clean.
Giacomo answered all my questions over whatsapp and contacted me about check-in with all the necessary details, even before I realised I need them. :)
So, overall experience with Giacomo and his apartment was a good one and I recommend it for: positioning, cleanliness and space.
