This Helsinki sauna can be rented together with its lounge areas for all kinds of occasions, and the space also works as a meeting room. The facilities are modern and well kept, and the website describes the atmosphere as that of a genuine kelo sauna (kelo is naturally seasoned, dead-standing pine).
Bookings are made through the reservation page on the website, and booking ahead is recommended. There is a toilet but no restaurant, and the website is in Finnish only.
