The ground floor has direct access to the basement, where a bigger restaurant and the hostel’s spa and sauna facilities are located. The restaurant can be used as cooling-off area for people using the sauna during periods when the restaurant is closed. The building was previously a bank, and it was decided that the reinforced concrete basement bunker should be left as a reminder of the history of the building. Inside the former vault there is a jacuzzi section, where the dark colour of the tiles is balanced by the alder-coated vault, next to which the sauna and toilet are located.
