In June, i went for the second time to Budapest, but this time i tasted the Budapest baths : the Gellért and the Szèchenyi baths. I preferred the Gellért baths because it is more calm and chic. The decoration is very beautiful and refined. The words calm, luxury and voluptuousness fit perfectly this place.
There are 12 pools : 2 indoor effervescent baths (one is 246m2 with 27°C water temperature and the other is smaller with 36°C water temperature) ; 3 outdoor pools (a 500m2 wawe bath pool with 26°C water temperature, a 94m2 sitting pool and one with 36°C water temperature) and 8 thermal bath departments (the water temperature varies from 21°C to 40°C). My favourites are the indoor bath with 36°C and the outdoor pool with 36°C. It was very pleasant and beneficial.
