Has anyone information about this sauna? It looks like that could be a "brazilian style sauna"...

It is not like a Brazillian-style sauna. Another member wrote are really good write up on this spot -- it is the back of the same building where Phisicus Spa (Avenida 2 Norte) is located.  Check the gay Colombia boards as I know a couple of members have posted good information about the Cali scene there.

This club was renovated in January as part of their 25th anniversary.  This is probably the most popular men’s (sex) club in Cali that isn’t called Black & White. 
 

There are three floors. The main floor has two lounge areas and the « straight » porn room. There are washrooms with « cleaning » tools on this level. The small locker room has been tucked behind the reception area. There are pool/billards tables here and a labyrinthe room with glory holes has been added.
 

Second floor has a large sex bed where they have strippers and interactive sex shows on theme nights. The private couples booths run along one side of this floor if you want privacy with your new friend. There is also a new large screen showing porn installed over the stairwell. 
 Third floor has been expanded and opens up — you can have a beer in the sun here. The bar has been doubled in size and because of the outdoor space you can smoke here.  The third floor also has the connector room with Phisicus sauna next door via a grated wall with glory holes. This is usually the busiest spot in the club. 
 

Gets busy late afternoon, after 6pm and into early evening.  Real mix of crowd, you should be able to find something to your taste. Also noting the hot kid selling swim and underwear on the third floor is also « working », several guys paid for a romp with him on the second floor. No reviews of his services to share.
