Ok
Ok for a swim!
Perfect
Can not understand how people give less than 4 stars for this place. Very great place for swimming, spacious, whirlpool and great saunas. It's more expensive though than the other indoor pools in Frankfurt. But definitely worth it. Most pools in Frankfurt you pay for the time you spend there, not the whole day like in the UK.
An OK place to spend some time in the water. The attached (nude) sauna, however, is definitely worth a visit. About a dozen saunas and steam baths, whirlpools, and even a cold room are just what the doctor would order if you asked them.
