I was there on a Sunday party naked with mask. The staff is friendly and helpful. Around 17:00 there were about 50 naked gays. Very sexy atmosphere, lots of action right before your eyes. A lot of dicks in erection, some really big and thick. Worth a visit!
Cruising bar. Sling is clean and with shower facility and besides its open every day. Therefor one of Vienna's most loved gay cruisebars.
