One of my favorite historical building from Milano, 

Cozy ambient inside, but also with tables on the street, Champagne Socialist is a good place to try natural wines from Europe. You can also go there just to buy a bootle (or more, of course) and drink it at home.

The owners were an industrial family of the XX century. We’ve been there a couple of times and we suggest it to every friend who is coming to town. You walk through the villa in the exact way they left it. You can see their personal pictures framed in the living room, their wardrobes and drawers full of stuff, like a pair of silk scarves especially designed by Monsieur Christian Dior for the sisters Gigina and Nedda Necchi, even the big marble’s bathrooms designed, like the entire house, by the architect Piero Portaluppi are inspiring.

Spazio Maiocchi is a social space where art, design and fashion blend to shape new cultural experiences. Originating from the convergence of visionary founding partners Carhartt WIP and Slam Jam, Spazio Maiocchi is a cross-disciplinary ideas aggregator, house to the studios and exhibition spaces of KALEIDOSCOPE, one of Milan’s most widely recognized enterprises for contemporary art.

Achille Castiglioni (1918-2002), architect and furniture designer, left an enormous amount of inventions and designs, carefully kept by his family in his studio museum in Piazza Castello.  Castiglioni's studio museum can be visited on appointment throughout the year.
