Well thats going to be fun.
I lived in Helsinki for a couple of years and Ive also sepent a lot of time in Vienna.
So things to see:
Esplanadi ( the main street in Helsinki is Gorgrous) Make sure to go into Capelli , its in the middle of the street and is a wonderful and beautiful old coffee house.
You can also stop in to Kampi and admire that beautiful Hotel , the bar is especially nice and all the best shopping is around there.
When you get done its a short walk down to the market . You can also take a ferry there to Suomenlinna ....
Now that is a must (remeber the ferry will accept a Tram ticket)
Let me say it again
Suomenlina is an absolute must.
Fair enough Helsinki does look a little like the poor mans St Petersburg but it is nonetheless quite stunnign for its architecture and wide streets.
Have a look at teh Orthadox Cathedrals whiel you are there.
Tallinn is another must. It takes just 15 minutes by helicopter and when I was there it was only about $100 to do that. Sure beats taking the drunken Finn booze cruise ferries.
In Vienna make sure you get to the restaurant on the top of Leoploldsberg.
Also you have to check out Hofburg , Schobrun and the Zoo , head up to the 19th district and while away the hours in a Huringer.
Also slightly off the beaten track is Oberlaa , its a marvellous Hot Spring / health spa where you can easily spend hours and hours.
And you might enjoy watching the Lipanzer stallions training.
Im outta time here but I'll let you know of any onther places as I think of them
