I was a little concerned about all the negative reviews for this place but I ususally take reveiws with a pinch of salt as everyones opinion is different.
The doorway to the entrance is a little hard to find when you've never been before. The entrance is a lift inside a small doorway next to lips, it has no external markings, probably for safety reasons. Press number 6 button and away you go.
The man on the reception was polite and welcoming. He explained everything to me and I chose a room with a bed. It's not cheap for a first timer but NY isn't a cheap city to start with. There are 3 floors inside, the floor you enter on has lockers, a small sauna which holds more than 3 people as previously mentioned, some guys clearly like to exagerate and a small steam room. They were clean and well maintained. The upper and lower floor has the rooms with beds. My room was clean and smelled fresh. Sauna corridors are warm. There is also a small tv room on the middle floor with everyday tv channels.
The guys are mostly older which I prefer but there were a few younger guys. I had fun so couldn't ask for more.
I have been to saunas all over the world and this one is no worse or better than most. Use it or lose it. Go to have a good time and don't blame the surroundings if you don't.
