The arrival window, from confirmation to the door
The arrival window is the forty to sixty minutes between a confirmed booking and her knock at your door, the same in every part of central Amsterdam.
The arrival window starts when the booking is confirmed and ends when she knocks. In central Amsterdam it is forty to sixty minutes, in every neighbourhood and at every hour.
When the clock starts
Confirmation starts it, not your first message. On a booking that carries a deposit, she sets out once the deposit has cleared, so paying promptly is the way to keep the window short. On a returning guest's same-day hour or two, confirmation in the thread is enough.
One figure for every neighbourhood
A flat in the Jordaan, a serviced apartment in the Zuidas and a room in De Pijp all sit inside the same window. Being close to the canal ring does not shorten it. The house publishes a single figure because a faster promise to one address would simply become a slower one somewhere else.
Using the window well
Forty to sixty minutes is about what an old Amsterdam radiator needs to warm a bedroom properly. Long-stay guests learn to turn the heating up the moment the booking is confirmed rather than just before she arrives. The same window is enough to close the laptop, swap the ceiling light for a lamp and clear the bed.
Schiphol
The airport and its hotels sit outside this figure. A booking there is arranged separately, with the journey time agreed with you before anything is fixed.
