Datariina is a business building at Heikinkatu 7 in Kotka, Finland, with seven bookable rooms for meetings, training days, small parties and sauna evenings. Rooms hold 10 to 100 people, and the venue says its meeting spaces cover groups of 8 to 100. The building stands near the centre of Kotka, on the island of Kotkansaari, and has a lunch restaurant on site.
Seminars and company events
Datariina offers rooms for meetings, team sessions and strategy days. Several rooms can be used at the same time, so parallel events are possible. The largest room, Optio-sali, is a 135 m² hall for 40 to 100 people and works for a plenary, a training day or a company celebration. Netti is a 64 m² training room for 20. Four smaller meeting rooms take 10 to 18 people each, which suits breakout groups or a leadership session.
The entrance lobby can also be used for events when agreed in advance, as far as possible. A reception desk service helps with room booking and furniture arrangements. Rooms are reserved through an online booking calendar on the venue's website.
Weddings and receptions
The site does not sell weddings. It states that small parties and events can be held in the rooms, and the sauna rooms suit a relaxed evening for a team.

History and setting
Datariina is owned by Kiinteistö Oy Datariina and the building is let mainly to companies. Its lobby, restaurant and parking serve both tenants and visitors, and meeting guests share the building with offices.
Getting there
Kotka is 134 kilometres from Helsinki. Customer parking is in front of the building, next to the main entrance, with a parking disc.

The venue says there is ample parking nearby and electric-car charging, and that public transport connections are good. The meeting rooms sit beside some of Kotka's parks.
