Went there yesterday. Very friendly staff, helpful and informative. There is a bar, darkroom with a cage, a large matress in the middle, some small cabins. The weekly themes are very well chosen and nice. Really a place where one can be free expressing your fetish. I prefer naked nights.

We went to Alcatraz with three friends at 2:30 on Saturday, we were received by a very nice guy who told us to wait at the entrance to pay. When the manager, owner came, he immediately behaved in a very unpleasant way with one of us. Coincidentally the oldest, a 77-year-old man. We let the situation go and went inside. We were going to leave the clothes in the lockers and again the unpleasant staff member comes, attacking our friend, this time because he couldn't find the locker and because he had the payment receipt in his hand, absurd right? Not happy with this, when we were going to leave he started picking on him again because he said he was older and that he was being silly. In reality the fool is him. The situation seemed surreal to us. We cannot say anything about the rest of the staff, they were super nice.

This place was fairly empty on a Friday night (01:00 hours), people allowed to smoke and as this place is underground with no ventilation I immediately left, would not go back, also it’s hard to find and a 10 minute walk away from much busier places
