Cancelling a booking here never brings its deposit back, whatever the notice; accepted force majeure turns it into credit, and an early finish returns nothing.
The rule is easiest to follow through a single reservation. A guest books Milena for three hours next Thursday. The office accepts, EUR 270 clears, and from that moment several things are already done: her evening is closed to other guests, other enquiries for those hours have been declined, her travel has been arranged. If the guest cancels on Monday, none of that is reversed, and the EUR 270 stays with the house.
There is no refund for cancelling early, no twenty-four-hour window and no percentage returned for a week's notice. Notice given afterwards, however generous, arrives when the cost has already been carried.
Two grounds are considered, each case on its own facts: a government ban on operating, or an illness serious enough to prevent the service. Where the office accepts one, what was paid converts into credit for a future reservation and is never paid out. A diary clash, an overrunning meeting, feeling slightly unwell, a rescheduled flight or simply changing one's mind all count as cancellation, nothing more.
Sometimes a reservation is accepted before any money moves: a regular's same-day hour, or a request taken while she was already in a taxi. Cancel one of those and the office has spent exactly what it would have spent anyway, so a cancellation-collateral payment is asked for afterwards, sized to match what its deposit would have come to.
A session the guest brings to a close before its booked length earns back neither the full fee nor any share of it. If her safety or consent is compromised, a woman from the roster may end it at once, and no refund follows.
Start with the general rule. Someone buying a service at a distance from a Dutch business would ordinarily be allowed a fourteen-day period to withdraw, under the Wet Koop op Afstand, the Netherlands' implementation of the EU Consumer Rights Directive. Then the carve-out: Article 6:230p of the Dutch Civil Code, in its date-specific-service exemption, takes out of that rule any service bound to a given date or a fixed stretch of time. Every reservation here names a woman, a day and an hour, so it falls within the carve-out. The fourteen days never begin to exist, and the house policy decides the matter.
