We spent three nights here and found it to be very comfortable and for Helsinki, even reasonably priced.
The hotel itself is in an old building from the outside but the interior is modern and very well done. Rooms have complimentary internet with desk, double bed, coffee table and sofa (our room at least). The only problem were no blinds, which during typically light nordic nights is a bit of a problem as the cloth curtains didnt block all the light.
Bathroom as good size with a bath and plenty of room for two people at the same time - judging by the other reviews of this hotel, there are differences in rooms and room sizes. We had room 610 :-).
Location of the hotel is conveniently central, albeit not in the nicest area next to a road.
