Erotic massage studios in Oslo, while not brothels, do offer a chance at a happy ending and even full service in some cases. People say that most Thai parlours do handjobs for a €50 tip. The rare cases of full service will set you back around €200. Just don’t think it’s a common thing; the ones that go that far are almost impossible to find.
If you’re just in for a sensual massage experience you’ll have to dish out at least €150 for the basic stuff. Angel’s Massage (https://www.angelsmassage.eu/) has two salons operating in Oslo. One is close to the Royal Palace and the other one is located around the Aker Brygge. Thai Aroma (http://www.thaiaroma.no/) at Dælenenggata 12C is your typical, relatively cheap studio with cute Asian girls. Sunrise (https://tantraoslo.no/) at Lille Frogner allé 5B, offers a fine selection of local masseuses and sexy tantric shenanigans.
