Great old Hamam!

Ideal to unwind after a long day of meetings (or sightseeing) for a bit over an hour. There's a separated male and female section. Main entrance hall holds a small cafe, on the upper floors are the male changing rooms. There is a separate changing room area for women. Between changing rooms and actual hamam are passage rooms with extra towels,  Door to an "old fashioned" urinal wall and a place for the washers/masseurs to sit.

Just go inside, give your chip you got at the register to a masseur and just crash on the gigantic marble center stone. After about 15 minutes the washer/masseur comes to you and washes everything you haven't covered with some type of towel (and you do need to keep your family jewels covered at all times, but you can use it as a lioncloth and the masseur should do your hips too). He'll wash and massage you for the next 10 minutes, really good!

After that you can go into one of the many smaller washing rooms to finish of the parts he didnt do, use the taps and open both hot and cold water!  You can return to lie down on the big center stone, but you'll just start sweating a lot again, and you won't get a 2nd treatment, so it's better to get back out.   Here you'll get a new (dry) "towel" around you (just face your back to the guy handing them out, he'll hold it open and hand you both ends of it so you can close it in all privacy)

Go back up, change, and don't forget to tip the guy sitting at the stairs of the changing room floors (after all > he looked after your changing room for about an hour). After all this, have a drink in the courtyard if you feel like it, but you can just go out and enjoy the city.
