Information about the public transportation and ticket prices in Helsinki area is provided by YTV. A single ticked for one region (Helsinki, only, or Espoo, only) costs 2.20 EUR, while a regional ticket (in Finnish, "seutulippu") for two or more regions (Helsinki, Espoo, Vantaa, Kauniainen) costs 3.80 EUR. If you plan to travel by bus/tram during your trip a lot, you might want to consider purchasing a tourist ticket for 1, 3, or 5 days. The Journey Planner is a very handy tool for selecting the proper bus/tram lines, for showing the routes and stops on the map, etc.
The Helsinki-Vantaa Airport is located in Vantaa. A taxi journey from the airport to the Radisson SAS Hotel Espoo (near building no. 28 on the map of Otaniemi; street address: Otaranta 2, Otaniemi, Espoo) takes about 35 minutes and costs about 40 EUR. Taxis leave in front of the entrance hall of the airport. Another option is to take the Airport Taxi, which is a bit cheaper.
Alternatively, you can travel by two buses, which takes about 70 minutes. First, take the bus 615 from the airport ("Lentoasema") to the very last stop in Helsinki City Center, namely the Railway Station Square ("Rautatientori").
