If you're in Cadiz drive up the AP-4 towards Jerez. Take the airport exit (Airporto) and follow the signs towards the Airport. About 2-3 minutes before you get to the airport you'll see a "Hote Club 96" on the right. There's only one exit to get you to the building so it won't be hard to find.
Just find a place to park and when you get to the front door you'll pay either 7 euro or 10 euro to get in. 10 euro will get you a free drink but pay seven because the prices of drinks are anywhere from 6-10 euros anyway.
I've met ladies from DR, Brazil, Colombia, Paraguay, Cuba, Venuzueal, Romania and one from Hati. If you speak a little Spanish you'll be good to go. Some girls speak English but not too many. I've only met 2 women that are from Spain inside.
1/2 hour is 60 euro and 1 hour is 120 euro. Some girls are willing to negotiate. You can pay cash or with credit card. The credit card charge will about 5-7 euro more. There's no ATM machine inside.
Just tell the girls what you want and they'll let you know if they do it or not. I've only found one willing to do anal, but then again i'm not too big on anal so I don't ask about it that much. Most will do BBJ but FS is always with a condem. Some girls say that some Spanish guys refuse to wear condems but I've never asked because I'd rather wear one.
I've been to this place about 8-10 times so if you have any questions just ask. I know of 3 others that are pretty good but give me a day or two and I'll post good directions for you.
Keep in mind that almost all places that have the word "Club" in neon lights are brothels. Prices vary from place to place.
