Mauritius Hotel & Therme
Spent your night (or day) at the Mauritius thermal bath with several saunas. It's a rather small place, but not as crowded as the bigger thermal baths (Claudius Therme, Neptunbad, Mediterana).
Schöne Sauna/Therme/Spa mitten in Köln. // Nice sauna / spa located in the center of Cologne.
