Staying here was an amazing experience. The rooms offered are either traditional or modern we tried both and it was like moving hotel rather than moving along a corridor. It is beautifully located for discovering Helsinki and the bar at the top provides wonderful city views morning, afternoon and evening. There is a friendly bustle about the place and the rooms are clean and well equipped. The breakfast buffet was superb but we tried the restaurant one big and found it unmemorable.

Spent a few days in this hotel just after Christmas. The location is in the center of it all, just a minute walk to the shopping areas and sites.
We had a regular room on the 2nd floor and it was massive! High ceilings, bright colors and a really nice bathroom with a beautiful bathtub.
Internet was free and the connection very good.
Breakfast had a decent variety. Not the most impressive layout but good nonetheless.
Visiting the bar upstairs is a must-do! It is the best view of the city. But it does get extremely crowded so get there early. Maybe take in the view first when getting off the elevator in case you're unable to grab a window seat. I suppose it's better in summer because there is an outside terrace as well. Drinks are very expensive but that is Finland.
The staff was kind and helpful in giving maps, info about the city and choosing a place for us to have dinner. We went just across the street to Karl Johan. Great food and quite good prices by Finnish standards.

I would definitely stay here again.

We stayed at this hotel during Christmas 2011 (got a super rate online).
Would recommend an online booking for this hotel as you get good rates.

Very good location, at the centre but not in a noisy quarter. The staff are very courteous, the rooms are good, the breakfast is solid and the roof-top bar (Atelje) has good views - what's not to like?

The hotel is very nice. We spent 3 wonderful days there in January 2012.
Among advantages I can mention polite staff, clearness of the room, location. The room was very spacious and the bed was cozy to sleep in. Buffet breakfast was fresh and various.

But there were also a couple of minuses: it was rather cold in the room so we had to curtain the windows off. The radiator was in good order though. The wind came inside through old and shabby windows. Also I saw a couple of insects in the bathroom.
