If there were, say, two of you, I could maybe help out, but four people is a bit complicated... Not enough blankets and mattresses to accommodate you all, lol.

I have a living room to spare, but my couch is too small for a male person, I'm sure - I can just about sleep in it and I´m 160cm tall. (Any girls in that group of yours?) Other than that, two mattresses are available. If you think you can share them between yourselves and really can't find any other place then I'm ready to give a helping hand.

Oh, and I do live in Helsinki, not exactly within walking distance of the Stadium but a fifteen minute bus ride away.
