If you choose 1 sauna in Athens, this should be it. The others are dirty, old, and depressing. Alexander is very clean, well organised/designed place, friendly helpful staff, European quality sauna, 4 floors, central, HOT guys, especially late weekend nights after people come from the nearby clubs. They have a good deal: 2-entry pass for EUR23. I heard about rent boys, but I never saw anything when I was there. Go have fun. Its near the subway metro station Keramikos. They have a good deal: 2-entry pass for EUR23.
Alexander Sauna in Athens is a huge and popular gay sauna on 4 different floors. It also has it's own special relax garden.
A variety of daily theme nights: Partners Day on Monday, Bear's Nights on Tuesday, Under- Swim- and Sportswear for boys up to 30 y on Wednesday. For the theme party a special area is reserved and guarded by a door man.
Busy, cruise, popular amongst local youngsters because of the little entrance fee they pay (only 7 euro). This sauna is nothing compared to other European sauna's (like the ones in Germany, UK, the Netherlands and Switzerland for example) - but foor Greek standards it is ok. It is clean, slippers are handed out to you at the door and first timers get a tour from the friendly staff (but they have to as the infrastructure is poor and the place in general is very dark and feels like a labarinth) - you would never find the lockers on your own, if the staff did not show you where they are).
