We really enjoyed this sauna while in town. Nicely located in Central Madrid. These saunas can always be questionable...however, this was very very clean, friendly staff and nice facilities. Plenty of space for privacy or for groups. It is all below ground in sort of tunnels, and I thought it might be musty or tight feeling. It is not. There are fans (dehumidifiers?) going in areas which are perfect. A couple of shower areas, large steam room, small-ish sauna, a bar/social area etc. We went a couple of times during our visit. It seemed on Sunday that it was a larger late afternoon crowd as people seemed to be leaving around 6:30 or so. As with all places, it's hard to know when the trend of people is. But, no matter, very relaxing place. read more
