Frankly spoken I didn’t expect much from the erotic massage scene in Gdańsk. In fact, there was no such thing just a few years ago. Sure, there were massage studios, but there was nothing erotic about them. Times changed and there are actually a dozen very solid (sensual) massage parlours in Gdańsk. I haven’t been in all of them, but I heard full service isn’t really on the menu. Getting a hand job finisher is quite common, though.
Ambrozja (http://www.taniecerotycznygdansk.pl/) at Cygańska Góra Str. is a decent pick. The owners even run a peep show joint. Massage Clinic (https://www.massageclinic.pl/) at 120 Jacka Malczewskiego Str. is fine too, although a little hard to find. An hour of erotic massage in Gdańsk will cost you around €50, which is pretty cheap.
