Yes, this hotel is really the worst place I've been in my life. And I paid for one night 59€. The information they give in internet is totally erroneous. it's a pity that I didn't take photos from the hotel.
First of all, it's not a Hotel, it's a pension. And a sad, dark and over-paid pension.
In the breakfast room, all the glasses, forks, plates, etc are different. I had breakfast with a fork that say "Hotel Thermal" (a big hotel of Karlovy Vary).
Please, if you are thinking on going to Karlovy Vary, try to choose another place.
