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.
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.
A polite administrator, with whom issues of renewal can be easily resolved.
