I booked the junior suite. It is located in the corner of the 5th floor. So the panorama view over the Ruoholahti residential area, the Ruoholahti Canal, the Crusell Bridge and the Baltic Sea is amazing. I especially loved the large balcony with sea/canal view. It was great to sit there and watch the sunset. Besides, the view was good even from the bathroom (and the sauna) but unfortunately windows were a bit dirty. I think that you can't get better view anywhere else in Helsinki than in this junior suite. Standard rooms haven't quite as good views.
Prices are very reasonable in this hotel because they haven't any check-in services or breakfast there. You only get a key code by e-mail or by text message 30-60 minutes before your check-in time. A shared laundry room, a shared mini kitchen and a very large shared living room with three microwave ovens, many table groups and a coffee machine (with charge) are available.
This hotel is located less than 2.5 kilometers from the city center, 1 kilometer from the West Harbor, 700 meters from Ruoholahti metro station and next to Crusellinsilta tram stop. I walked from the central railway station to the hotel. It took 30-40 minutes. There are very beautiful walking areas near the hotel, too. I especially recommend nearby parks, especially Saukonpaadenpuisto and Hyväntoivonpuisto.
