I second this. There are a number affordable hotels in Helsinki; you should check out Cumulus, Scandic or Sokos brand of hotels in Hakaniemi, Kallio, Kaisaniemi, etc. Also Forenom has several apartments that they let for 1-2 days. I use my Avios points to pay for my hotel stays in Helsinki. There are a lot of things you can do in Helsinki for two days.
