The price of these baths was what first made us decide to visit. We bought student tickets for 1700 HUF each which seemed much more affordable than others that we looked at visiting.
The baths themselves are amazing. They haven't been redone in a long time (since the 1950s I think) but this adds to the character of the place. There are lots of baths with different temperatures as well as a steam room, two saunas and a jacuzzi. Over the main bath there is a beautiful dome which adds more charm to the place.
There seemed to be a lot of locals using the baths and it definitely didn't have a touristy feel- something which made the experience more authentic. The baths are also mixed so perfect if you are in Budapest with a partner. If I went back to Budapest I would go again.
