Club 3000 is still in activity (limited) according private forum.

User probably make reference on possibility to rent small kot for short use. 

But the outline here is not correct , for this POI and for housenumber 5 to 17A. Urbis is false. 

Former cinéma Orly was housenumber 9-11 : https://www.memoire60-70.be/Cines_Quartier/Anciens_cinemas_Saint_Gilles.html

Club 3000 is here : https://www.openstreetmap.org/way/264074827 (with the sunbath rooftop)  and https://www.openstreetmap.org/way/264071542 with housenumber 9

On https://www.mapillary.com/app/?pKey=181172651104417 there is 3 projectors that lighting the flags and the facade of the sauna. 

And 2 projectors that lighting the lateral of the hotel (with signs) : https://www.mapillary.com/app/?pKey=520635639461190 

So Hôtel Midi is here https://www.openstreetmap.org/way/264074849 with housenumber 11.

For the POI itself think
gay 	yes
leisure 	sauna
lgbtq 	primary
is better than public_bath
