Tnt, you should. Helsinki is a wonderful travel destination to spend a long weekend. Loads of things to see, a lot of nice restaurants. It's best in Summer though, and one reason it's not a more popular city for tourists is that it's a bit expensive. Another great thing to see in Finland is Lapland. You can easily spend a week or two there in Winter if you like skiing and other snow related activities. In the summer Lapland is pretty beautiful too, but there's less to do. It's mainly built around winter sports. The nightless night is pretty cool though. And if you want a active holiday in Finland, the archipelago is beautiful. Renting a boat is a nice idea, you can spend a month sailing around there.
