Wow - went today - on a Tuesday afternoon between work and a business dinner - maybe 4-6pm. Great space - lots of rooms and well laid out. Clean, and as common in Europe- a full service bar so you can get a drink and relax. Gym, hot tub, steam room, sauna, showers, porn playing everywhere ....and great play space.....and the thing that amazed me the most - it was really busy! I would guess minimum 40-50 guys....and a wide range of ages and types. While skewed to middle aged, there were some really hot younger guys and a mix of some older - way more guys than I would ever expect to see state side on a Tuesday afternoon. And lots of action going on.
Definitely worth 21€ and a visit. You will find satisfaction here if this your scene.
