I cannot recommend Royal Spa, or particularly the specialist Dora, more highly. I have been to spas/ baths literally all over the world, and this one is my favorite. It was clean, beautiful, had the full range of relaxation offerings (swimming pool, hot baths, steam room, sauna rooms, and quiet areas to rest), and the staff was amazingly helpful. I had a mud wrap with Dora, and I give her a 6 out of 5 stars. Amazing, not to be missed, experience. Budapest is a wonderful city, worth a visit, but this spa is so good that if it were out in the middle of nowhere I would still make a point to visit it again. I'll be back!!
