First of all, what a wonderful location: Right in the heart of Helsinki's chic design district, just steps away from great bars, restaurants, record stores, bakeries, and more. The city center is a quick walk away, or there is a tram stop directly in front of the hotel.
The hotel itself is chic and modern, with subtle old-Norse accents (antlers, animal pelts, eerie folk music, etc.). The room was spacious and incredibly well-appointed -- complete with in-room sauna. Plenty of USB plugs, too, which is always a plus.
Breakfast was a bit crowded, but given the quality and variety of food offered, not surprising! Service was very friendly and efficient.
Also, the hotel restaurant serves delicious Finnish food and is worth dropping by for dinner...
