A first booking with the house
A first booking is any client's initial session with the house; it carries a deposit of half the fee whatever its length and however soon it starts.
Every client books a first time once, and on this site that first booking has one fixed feature: half the fee is paid ahead, whatever the length and whatever the hour. For visitors on a first trip to Amsterdam this is almost always the case, since the city and the house are both new to them.
Why a first booking carries a deposit
A first booking is the one where neither side has any history to go on. The deposit makes the commitment mutual: she keeps an hour free for someone she has never met, and the client confirms that the hour is wanted. Be it a single hour or three, the confirming payment is half of that length's fee, so it grows with the time reserved and with nothing else.
What a first booking includes
Nothing is different in the room. The therapist decides what a session includes and explains her limits in her own words when she arrives, exactly as she would with a guest she knows. A first booking does not need to be long or elaborate; many first-time visitors choose ninety minutes of a slow oil format.
After the first
Once the house knows you, one kind of booking becomes deposit-free: a same-day hour or two at an address inside the city, paid in full on arrival. Anything else still carries half ahead, as the booking terms explain.
