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 • Ottomania, Aschebergsgatan 23, http://ottomania.se/oppettider.aspx • Johannebar, Eklandagatan 65, http://www.johannebar.se/ • Bryggeriet, Kungsportsavenyn 3, http://www.bryggeriet.se/index.php/restaurang • Sj¨obaren, Lorensbergsgatan 14 http://www.sjobaren.se/lorensberg/ Practicalities Contact T¨ unde +46 707 302927 or office +46 31 7723180 Adam +46 707 55 22 55 or office +46 31 772 3192 Mia (secretary) office +46 31 772 3212 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 Park Avenue. Tickets can be bought online in advance or onboard (but only with credit cards). More info at: http: //www.flygbussarna.se/en/landvetter. It is not far from the hotel to the university and the easiest way to get there is by walking (15 min), as shown in the figures. 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 Korsv¨agen or at Seven Eleven at Vasaplatsen (close to the hotel). 5 Figure 1: The easiest route from the hotel (A) to Chalmers is to take Aschebergsgatan. You can find the map under http://goo.gl/maps/b6Jg4.. An alternative is to take trams 7, 10 or bus 16 from Vasaplatsen to Kapellplatsen (just one stop) or Chalmers station (one more). A map of G¨oteborg can be found here: http://www.stadskartan.se/goteborg/ For those who like to bike, you can read about how to loan one here http://en.goteborgbikes. se/ 6 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. 7
