there are 3 more turkish baths in BP. 2 really Turkish, 1 is similar like this one, includes partly. Unfortunately, only 1 is operating out of 3. I've been in an other one, what is under renovation at least for 1 more year, that has a bigger dome, too. I will post about that later, it didnt look so good, really needed some work on it.

Anyway the Rudas is popular amongst the local Turkish, too, i suppose mostly because the only bath in BP where are separate men/women days in the weekdays.
