The workshop will be in the Physics Department of the University of Milano-Bicocca. We're in room U4-01. The full address is
Universita' degli Studi di Milano-Bicocca
Piazza della Scienza
20126, Milano, Italy
This is the precise location:
Get to that address above. "Piazza della Scienza" is a big square with four big red buildings named U1 to U4 that look like this one, you can't miss them! There's a construction site right now on the square but don't despair.
The room is in building U4. You could enter the U4 building from its main entrance and follow the signs, but the easiest way is from the stairs in the center of the square, right next to the tram line (the sign says "Settore Didattico U3-U4", see picture). Enter there and go downstairs. Room U4-01 will be there waiting for you!
Milan has three major airports:
Milano Malpensa (MXP) is the airport with overseas flights. If you're coming to Italy from afar, the first thing you need to do when you land is getting a good coffee. Then follow the signs for the train station. There's a train service called "Malpensa Express" that will take you to the city center. The ticket is 13 EUR and you can buy it either there from the automatic machines or on the "Trenitalia" phone app. There are services to both the Centrale and Cadorna train stations. Any of them will work, the Centrale train is a bit more convenient for the Bicocca campus, so if you can choose pick that one (if you're on a train going to Centrale, you might want to hop down at Porta Garibaldi, see below). The last train is around midnight, if you arrive later there are additional buses.
Milano Linate (LIN) is a smaller regional airport, with connections to some European hubs. The airport is served by the blue line of the subway (M4). Buy a regular 2 EUR ticket (valid for 90 minutes) and take the subway to San Babila, which is right in the city center (can have a look at the Duomo while you're there, which is our outstanding cathedral). From San Babila, you can take the red like to Precotto and walk to campus from there. Or if you walked to Duomo, then take the yellow line, change at Zara for the purple line till Bicocca.
Milano Bergamo (BGY) is used by low-cost carriers (the entire airport is basically a Ryanair warehouse...). When you exit the airport, there is an endless stream of buses that will take you to the Centrale train station for ~5 EUR. Just get onto the next one leaving, they are operated by different companies but cost the same. You can buy the ticket from the guy just before getting on the bus.
Taxis in Italy are very expensive (and get stuck in traffic). Not recommended unless you plan to arrive really late or leave really early.
Maybe you're coming from the airport, or maybe you're coming straight by train from Italy/Europe. There are three main train stations in town:
Milano Centrale. Centrale is a majestic building with massive steel arches from the 1930s. Once you're there, follow the "M" signs for the subway, buy a standard 2 EUR ticket, take the yellow line to Zara, change to the purple line, and hop down at Bicocca.
Milano Porta Garibaldi. The Garibaldi train station is next to the skyscrapers of Gae Aulenti square and the Vertical Forest. So if you're there you might as well have a look. To get to campus, go to the subway, buy a standard 2 EUR ticket, take the purple line, and hop down at Bicocca. In case you're curious, Garibaldi was an Italian general and revolutionary from the 1800s.
Milano Cadorna. Cadorna is in the Milan fashion district. To get to campus, exit the train station and go to the subway, buy a standard 2 EUR ticket, take the green line to Porta Garibaldi, change to the purple line, and hop down at Bicocca. Cadorna was another general.
Also:
Milano Greco Pirelli. This is a little train station that is right next to the Milano-Bicocca campus. Using the subway is usually more convenient, but it might be worth checking the train times to Greco Pirelli as well.
Public transportation in Milan is efficient and reliable. The subway is open from ~5 am to ~midnight. A ticket for the inner zone ticket (Mi1) costs 2 EUR and covers most of the city for up to 90 minutes (and you can use trams, buses, subways, etc, for those 90 minutes). You can buy the ticket at the automatic machines or also just swipe a contactless credit/debit card when entering (yes, without a ticket). Note you won't get a receipt this way. There are also 10-trip cumulative tickets (which are called "carnet") where you pay only 9 of them.
The closest subway station to campus is "Bicocca" on the purple line. Station Precotto on the red line is also close enough (it's on the other side of the railway, you'll need to walk under the Greco Pirelli train station).
Tram line no 7 also stops right in front of the Physics department (and trams in Milan are kind of experience, you should try once; the lines date back to the 1880s and some coaches with wooden benches from the 1920s are still in operation).
Electric bikes and scooters are also a thing these days; you'll find them everywhere.
We did not negotiate special deals with local hotels, as we couldn't get anything better than what you can find on the most common travel websites. So please just book there. Airbnb is also a popular choice.
The University is located north of the city center, check out our Location page. The area around campus is nice enough, so anything close by would work. The department is west of the railway, but there's a convenient underpass, so staying on the other side of the railway is ok (the area to the west of the railway is arguably a bit nicer).
The department is very close to a station of the purple line of the subway, which goes to the city center. So really anything close to another purple line station would also be fine. The Isola area in the city center is very nice and very popular (hence more expensive than around campus).
One place we can recommend that is close to campus (and was used by several previous visitors to our group) is Hotel degli Arcimboldi (about 15m walking from the department).
Here is a map of the subway. Bicocca is toward the top of the purple line M5 (note that the M4 line from San Babila to Linate Aereoporto is operational!)
