If you are up for it, then take the 173 steps up the tower - you won't regret it
I can't really review the town hall it self, because we came late at night and it was closed - but we didn't come for that anyways, we came for the tower!
The fee is 70k (5€) and from there... It's just about getting to the top!
You get an amazing view of the city, all the cathedrals and life going on in the small streets down below.
Even though I'm in pretty bad shape and a heavy smoker - I would do it again
But remember; after 6 pm. they only take cash. Otherwise no worries, there is atm's close by More
