The Omena Hotel chain has done away with human staff. You just turn up, punch your reservation into the computer terminal at the door and are given a room number and access code.
You can even reserve a room on the computer if you haven't done so beforehand. For about 60 - 70 euros you get a modern room with widescreen TV, microwave, fridge and free wifi.
There are two in Tampere - the nearest one to the train station is Tampere II.
