Rhein Main Therme
This is claimed to be one of the best spa centers in Germany. It really looks great and offers lots of choices of activities.
In winter they make a great lunch which you can eat outside at the fire. Inside everything is light and the atmosphere is very fresh and healthy. Only one thing is bothering me: German naturalism. People are going to saunas and steam baths totally naked, which does not always looks nice...For those who doesn't want to see much more then people covered in towels and bathrobes that can be disturbing. Although by some time you may get used to that. [more ]
