Generally the facilities of the hotels are very good and one can have a good time enjoying the spa. What you should definitely take in to account is that the food was of very poor quality, meaning not fresh, mostly fat and fried, not well cooked, unvaried and lacking choice. We got even sick from one old see food sauce, so be careful. It could be worthy to spend twice the price and go in the superior Danubis Hotel with the same facilities, but quality of food. The hotel is not renewed, kind of soviet style furniture and old and very slow elevators could be a bit frustrating. The pools are also not renewed and with very sharp edges. I cut myself several times while swimming. If you a young couple it could be boring to stay more than 2 nights - most of the activities are for seniors and the fitness is very poor.
Indoor and outdoor pools even in the winter. Close to the biggest thermal lake in the world. In the hotel you can buy different spa procedures assigned by a doctor. The all inclusive includes breakfast, lunch and supper including wine in the lunch. The stuff was helpful and kind, though they speak not so good languages.
