There is a good sauna in Polna. A large recreation area. The pool is not very big, but there is enough space for children. Paris is excellent to heat each separately from the street.
I've been there many times, but as the owners changed, it didn't feel good. I forgot an electronic cigarette and a thing in the sauna, called several times during the day, brazenly said that there was nothing there, although I am sure that this is not the case. They either kept it for themselves or threw it away. I condemn this attitude
We were a company of 6 people. I liked everything: a spacious sauna, a banquet hall with karaoke. There are dishes available, but there is no microwave.
