The blaze broke out late Sunday night at The Steam Works club, in the “narrow and winding” small private rooms, making the search by the fire department more difficult, Times Live reports.
Over 80 rescue workers were dispatched to the scene.
“It was a lot of work to break into each room and to check for victims,” a fire department spokesperson said.
The club in the central Schoeneberg district and is described as being “made up of saunas and common areas, as well as 60 small rooms, each with a bed inside, and is a well-known meeting place for Berlin’s gay scene.”
One victim, a 48-year-old man, suffered from smoke inhalation and was taken to the hospital. More than 25 people escaped the fire on their own and helped point first responders in the right direction.
The cause of the fire is still unknown, reports the Associated Press.
