Hellsinki is a lovely city. We walked around and saw some churches, shopping districts, parks, and lots of water. Because Hellsinki is made up of several hundred islands, there are bridges and waterways everywhere.
I have to say that the city didn't wow me like the others that we visited though. It felt kind of "flat" though I don't really mean that. It just wasn't as "wow" as the others and our local tour guide was "eh"...
That said, I did have a lovely time in Hellsinki but I don't see much need to return.
Though seeing the ice breaker boats was enough to make me realize that I'm not hardy enough to live there :)
