They say, if you want to know a country better, you go to the countryside and not in the big cities.
OK., Milan is Milan, you ..smell the Italian fashion power in every step, but why not...combine both.
What I suggest below, is a fantastic option among others.
Dedicate one day, to the lakeside part of Lombardy, just 40 minutes drive to the north of Milan. Take A9, exit COMO NORD.
Undoubtedly, the rates are for people with deep pockets, anyhow the reason I suggest it as a shortbreak from Milan, is to have a nice lunch by the lake in a superb scenery. Special tip: Go for my favourite, lakefish for two, cooked with thin potatoes,olives,capers and boiled spinach on the side...Try as well their risottos, they are great.
If you have time after lunch, visit picturesque village of Bellagio, asking all the necessary information from the concierge.
Finally, if you leave this great escape from Milan for your last day, reaching Malpensa airport, from the Villa D'Este, will take an hour......
