Me and my husband have spent 5 relaxing days in April in this hotel. We were here several times in the last years, and we return this summer too. What the other travellers write, is totally true . I can't write other things, since I have read the reviews.
Also: the hotel is a real four stars superior quality, with pleasant rooms, good wifi, tv channels and... last but not least, with very comfortable beds. The rooms are refurbished, and spacious.
The whole hotel from outside seems to be a socialist spa hotel, but inside it is modern. Only the dining room remained "a bit from socialism". The food was correct, three times a week a buffet dinner, but on the other days you have to choose from 4 main courses. What really good is, that you can choose, whether you would like lunch or dinner in the halb pension. The breakfast choice is perfect, the dinner sweets are every time the same, nothing special. The drinks in the restaurant are overpriced, I think. But you can have fresh water from a marvellous Zsolnay-tap free.
The morning coffee is terrible - they had to modernize (I mean change) the old coffee machines.
The spa is clean and the swimming pool (28 C) can be used in bad weather too, because it's in the building. Very good, that they have two thermal basins with several temperatures, everybody founds his comfortable one.
The staff in the reception is friendly and helpful, which is very important, I think. The town is quiet, you can take long walks in the streets, and Keszthely and the lake Balaton is near.
I recommend everybody to choose this hotel, you can spend very pleasant days here.
