Naked Spa Madrid

Naked Spa, also presented as NKD, is a liberal spa on Calle Adelfas 16 in Madrid's Retiro district, about ten minutes from Atocha according to its website. The venue is split into three areas: the spa itself, with a pool, jacuzzis and water jets, saunas, a steam bath and massage cabins; a club with a cocktail bar and music where guests may wear clothes, lingerie or nothing; and an upper floor of open rooms for those who want to take part or simply watch. In the water area entry is nude, and swimsuits and lingerie are not allowed. Its clearest feature is the session system. According to the official website, the atmosphere and who may enter depend on the session: Swinger (couples and single women), SW Night (Friday and Saturday evenings), Open Bi (open to couples, men and women), Only Girls and Only Guys. The published rates include a locker key, towel, slippers and one drink, and they can change for events or promotions, so check before you go. The club also runs themed evenings listed with their own dates on its events calendar. The house rules stress respect: do not interrupt a game without an invitation, do not touch anyone without consent, accept a no politely, good hygiene is mandatory, and breaking the rules means immediate expulsion. Couples must enter and leave together, and guests may step out for about ten minutes to smoke while respecting the neighbours. It is a good example of a venue that explains its rules clearly before your visit.
