I had two nice experiences at the Japan Massage Parlour. http://www.japanmassage.hu/
Standard service is massage plus handjob for 15000HUF.
Some girls provide BBBJ to completion for an extra 3000HUF. You have to ask the girl, but anyway she will ask you if you like to have it.
First experience was with Maya. Very pretty girl with good massage skills. I was expecting a hand-job, but she offerred oral for 3000HUF that I could not resist. It's a fully naked massage, but you are not allowed to touch her.
Next experience was with Kitty. She speaks good english, and she made it clear on the phone that oral is not in the menu. I booked with her the jakuzi plus massage for 2 hours. What you get is an open-air jakuzzi at the roof-top with champagne and then an hour of massage and hand-job. Decent experience, although no sexual services are offerred at all.
Their place is downtown and easy to find. The apartment is on the 4th floor, and they have a clearly marked doorbell at the main entrance.
