Nice gay sauna with 17€ entrance fee.Sundays can be really busy, with lots of hot Spanish young guys. Just bring extra condoms they only give you one. The sauna itself is nicely decorated in antic style and clean. You'll find a dry sauna, hammam, swimming pool, play rooms, a space with cages and slings, private cabins, a video room etc... Absolutely worth having a look if you're in Madrid and horny!
