Hotel Please mail anne.seilonen@chalmers.se if you want to book a room in Hotel Po-
seidon (where many of the other participants are staying).

Transportation The cheapest way to get from the airport to the city center is to
use the airport bus. It leaves every 20 mins and takes about half an hour to get to
the city. The stop which is closest to Hotel Poseidon is Berzeliigatan. Tickets can be
bought online in advance or onboard (but only with credit cards). More info at: http:
//www.flygbussarna.se/en/landvetter.

Restaurants nearby The lunches (Tue-Fri) and the dinner on Wednesday is free of
charge for all participants. For the other meals: there are plenty of restaurants near
Avenyn and close to hotel Poseidon, and also a lot of pizzerias and sushi places along
Gibraltargatan. The following are just suggestions.

   • Smaka, Vasaplatsen 3, http://www.smaka.se/eng_meny.html

   • Krakow, Karl Gustavsgatan 28, http://www.krakow.nu/

   • Johannebar, Eklandagatan 65, http://www.johannebar.se/

   • Sjöbaren, Lorensbergsgatan 14 http://www.sjobaren.se/lorensberg/

   • Natur, Geijersgatan 12 https://www.restaurangnatur.se/

It is not far from the hotel to the university and the easiest way to get there is by walking
(15 min). For those who want to use public transportation, the easiest is to buy a tourist
and visitor card: http://www.vasttrafik.se/#!/en/2/6/ This is sold for example at
Korsvägen or at Seven Eleven at Vasaplatsen (close to the hotel).

Figure 1: The easiest route from the hotel (A) to Chalmers is via Aschebergsgatan. An
alternative is to take trams 7, 10 or bus 16 from Vasaplatsen to Kapellplatsen (just one
stop) or Chalmers station (one more).

Figure 2: The two easiest ways to enter the building and access the PJ room, where the
meeting is located, are shown on the map.
