Just got back from Budapest. Some of the best spas I've ever been to are there. I particulary recommend the spa at the Gellert Hotel. Admission was a little less than $7 US, and entitled use of the many indoor and outdoor thermal pools (all were warm, some just luke warm, some toasty like bathwater, and some were ha-cha-cha hot like a jacuzzi) the sauna, the steam room and the mineral baths. Spa treatments like mud, facials, massage, etc. were extra, but also ridiculously inexpensive. A massage was less than $8 US. Most of these spas were built by the turks several centuries ago during the reign of the Ottoman empire. They are quite ornate and lavish and have been kept up nicely despite their age.
