Getting there
Getting from the airport to the seminar hotel is easy.
Apart from regular taxi or a group taxi you can take either of the two buses, no. 615 or Finnair. Their stops are at the front of the International terminal. Click on this link to get to Hotel Arthur's page of advice. It includes a map of the centre area covering the hotel, the bus terminals and the main railroad station, all close to each other.
Below is a map of the location of the bus stops and taxi stands at the airport. The stop for bus 615 is at 1B "Local Buses" and Finnair bus stop is at 1A.
