Carlo is really carrying host. The apartment is small but very cosy. There's nothing we can thing of that was missing - fully equipped kitchen (except for a microwave), some snacks and water for us (thank you Carlo!), iron and ironboard, enough space for clothes, towels and sheets.
Bus 47 stops 10 m from the building and the center is easily accessible by public transportation (subway is just a few blocks away). The neighborhood is safe, has cafes, restaurants, supermarkets and pharmacies. It takes about 15-20 mins walk to Naviglio Grande where you can find some of the best little restaurants; it gets very busy on Sundays with the antique market, handmade market, art shops... Carlo showed us on the map where to go and where not to go for fun and good food, sent us a list of good restaurants to visit and was replying to all our messages immediately which really made us feel secure about our travel and stay in Milan.
It took us about 2 hrs from Bergamo to the apartment (1 hr from Bergamo to Central Station and another 1 hr from the Central Station to the apartment).
If you have to catch a flight early in the morning (ours was at 0740 am) from Bergamo, trolleybus 90 (starts at 3 am, every 30 mins) will take you to the Central Station (about 45 mins ride in the morning) where you have shuttles to the airport every 30 mins.
We really enjoyed our stay, loved the apartment and will definitely come back when visiting Milan again one day :)
We very much recommend Carlo's place for a short stay in Milan! Thank you Carlo!
