I did this trip not so long ago,I stayed at the Holiday Inn Vantaa,miles from the airport,it was -4 when I arrived,the free hotel shuttle bus failed to arrive,so had to get a taxi,who,got lost and tried to rip me off!!But got to hotel,which was nice,used the free shuttle to the airport in the morning,then the Airport Express Bus in to town,simple!!! Helsinki was nice,if not damn cold.The flights by BA were excellent.CE out,and pleb class back,but actually the trip home was much nicer,chatted to all the crew,had a fab time,plenty of Gin and Orange....^
