The Clarion Hotel Helsinki tower acts as an accent in the city structure when entering the new construction harbour area of Jätkäsaari. The neighbouring magazine building L2 (designer Lars Sonck 1935), is a good example of 1930´s late-classical industrial architecture and is connected directly to the hotel lobby. The seven meter high lobby connects the 14 hotel floors to the event and congress centre of the old harbour magazine.

The hotel floors consist of 425 varying sized rooms with a sky bar, sauna, pool, and fitness area on top. The sky bar and the cantilevered glazed-end pool provides the guests with a spectacular view over the Baltic Sea, harbour, and the city of Helsinki. The ground floor also houses a café and bar with outdoor areas along the harbour bay.
