Sauna Príncipe, gay sauna between Gran Vía and Plaza de España

A classic old-school sauna on the Beatas cross street, halfway between Gran Vía and Plaza de España. People who know it talk about a crowd of mature men and bears. It has a jacuzzi, dry sauna, steam room, two maze levels, around twenty cubicles and two dark rooms. Opening hours are not fixed: plan on going from midday to midnight, and check before you leave.
