As an American who has traveled to different countries and enjoyed other spas, DO NOT COME TO THIS…read moreSPA IF YOU ARE AMERICAN. I came with three of my girl friends, thinking we would have a relaxing and clean experience. The heated pool is filled with poop particles. We thought it may had been one person in one area, no! Walking around it, it was FILLED with fecal matter. You could not look down into the water without seeing brown and yellow clumps, fibers, and specks. I know some hot springs will have minerals in it, but this was not that. I also experienced something extremely odd in the showers, there was moaning several times. And my friend saw throw up or another bodily fluid in the showers as well. The fact there is no worker maintaining the shower and spa area mind boggles me. I cannot believe my friends and I paid for this experience. I would NEVER recommend this spa to a friend or family member and hope this can help anyone who is deciding a spa to go to in Karlovy Vary.
