Considering we went here in the first week of march and temperatures were about 8 degrees, you didn't actually feel the cold too much in the outdoor pool.
Fees for two people using one "cabinet" which is a lockable dressing room are 9,100HUF there's no time limit, so you could literally spend the whole day there.
The outside pool is about 37 degrees. There is also a swimming pool - you must wear a swimming cap if you're going to use it.
Inside there are 3 parts. Lower floor there is a sauna, steam room and a cold pool, there's also a supply of salts so that you can give yourself a good scrub.
Upstairs there are two parts, to the left are the newer medicinal pool, in all there are about 10 pool ranging from 26 degrees to 38 degrees, all medicinal, there is also a few cold pools and steam rooms. To the right are the old pools - impressive red marble and sculpted columns with 1 large pool, a slightly smaller pool and a small pool, there is also a cold pool here too.
The only thing I would recommend is that you take two towels with you if you plan to use the sauna, as my towel was soaked after being in there!
