St George looks like an exciting old building to stay at. Shame it's not available when I'm planning my first time stay in Helsinki, during new new years eve.
So have a reservation at Klaus for three nights and went for the Envy room. Didn't dare to pick the cheaper much smaller rooms considering new years eve and all. Bit pricey, 250€ inc brekfast and flex. Will see if the rate goes down a bit, usually it does during october-december when it comes to new years eve rates.
Haven't found any lower 3rd party rates but this is a design hotel so the brg is on crappy terms already.
