What you'll find in Utrecht
The erotic massage studios are part of the offer in Utrecht listed here, by appointment. The city, a central railway hub of the country, also shows a rich pool of venues within the Randstad.
The activity is fully legal. Hours cover afternoon and night, with weekends being the busiest. Amsterdam, The Hague, and Rotterdam are all a short train ride away and greatly expand the offer. Payment is almost everywhere by card or contactless.
