You are responsible to take care about you own travel arrangements.
If travelling by car, consider the option of travelling together. Bus and train station are not far away from the dormitories so you can simply take a 15 min walk. If you're flying to Sarajevo, check with your ISSS fellows their itinerary. Chances that some of you will arrive with the same plane are quite high since Sarajevo Airport is not so big and there aren't many connections, so you can share a cab. Unfortunately, that would be the only way to get to get to the dormitories since there is no shuttle or public transport to get you there.
MONEY AND BANKS
BiH currency is convertible mark/ KM or BAM. (1 Euro = 1,95 KM). It's easy to exchange Euros to convertible marks in many different banks in Sarajevo. Euro is not generally accepted, especially coins.
Throughout the entire summer school in the hostel lobby you will find the info desk, which will be available to answer all your questions and provide necessary information. All announcements (changes to the agenda, shuttle service etc.) will be displayed on info desk. Also, possible modifications will be announced each morning before the lectures.
