A friend and I went here one evening, to the common women's facilities, and we had a great time. While both of us speak a bit of Russian, overall the "what and how are we supposed to be doing things" part was a bit confusing, even though I'm experienced with banyas and saunas. But by getting friendly with some locals, with our okay Russian and their limited English, we were able to have a great time.
This is definitely the kind of place locals go to, with kids and their moms their, friends hanging out, and the like. The environment was friendly, and the facilities themselves were good.
Some things to keep in mind if you come is to bring a towel, a pair of flip flops/shower shoes, and probably soap/shampoo if you'd like, along with leaving your shame at the door. Don't be afraid to ask someone for help or even just get to know your fellow bathers, because while banya/sauna should be a relaxing experience, it's also supposed to be communal!
Have fun and relax on a cold Russian night with some new friends.
