I like the Volna Club. Small, cozy, only for women. The administrators are friendly. The coaches are just wonderful! The format of classes is interesting and effective (of course, if you regularly attend and study). And yes, there are discounts on season tickets, which is good news.
Compact sports club for women. Neat, clean. Several types of athletic activity. Friendly staff. All are young and progressive. I was at a free trial class. I really liked Tatiana's anti-gravity coach
