Yes, it has lockers, jacuzzi for about 6-8 persons, dark labyrinth with cabins (each has sofa, fan, paper towels) , dry sauna and steam room, all together is located on the edge of the pool. Locals tend to arrive about 5-6 pm and leave around 9 pm for clubs. Friday-Saturday are most crowded days, while at Mo-Tu there may be no visitors, so you will find yourself in sauna in company of other resort's guests.
There is also kitchen and "restaurant" + bar next to sauna and gym. Also there is massage room. All 3 times when I had stay there food was just average, massage also was so-so. Staff are male only, but almost all are friendly str8s.
As per my experience - the most interesting time to stay in hotel is low season: at that time there will be just a few resort's guests, so local will compete for your attention: once I had 4 actions just at one evening (3 locals + one young flight attendant from Singaporean Airline) .
