Forty to Sixty Minutes: What the Window Measures

Every page here says forty to sixty minutes, and a number repeated that often deserves to be defined properly at least once. It measures the interval between two events. The first is the moment the hour is agreed in writing, which means the address, the time, the length and the figure are all settled. The second is the knock.

Everything else people imagine it might include is outside it. It does not start when you first write. It does not start when you decide you want to book. And it does not stop when she reaches the building, because a building is not a door.

Why a range rather than a time

Because a single promised minute would be a fiction dressed as precision. This city puts bridges, trams and canals between most pairs of addresses, and any of the three can move an arrival by ten minutes without anybody behaving badly. A range absorbs that. A stated minute does not, and the only thing it achieves is a guest watching a clock and feeling let down at the sixty-first second.

Twenty minutes is about the honest width of the uncertainty for a central address. Quoting it is less impressive than quoting forty-five, and rather more useful.

The three things that push it to the far end

An address without a floor or a room number is the first. The last two minutes of a journey become a search, and a search in a building with a lift lobby and four corridors is not a short one.

A locked entrance nobody mentioned is the second. Plenty of buildings in the centre lock a street door after a certain hour or want a card in the lift. That is entirely normal and entirely manageable, provided it appears in the thread rather than being discovered from outside at half past eleven.

A phone on silent is the third, and it is the one that can undo a booking outright rather than merely delay it. If she cannot reach you from the street, the evening stops there. A phone left face up and charged from the moment the hour is agreed costs nothing and removes the whole problem.

What does not move it

The hour on the clock does not, because the journey is measured from wherever she happens to be rather than from a building with a sign on it. The district does not; the centre is small and the difference between neighbourhoods is inside the twenty minute spread. The day of the week does not. And nothing about any of it changes the figure, because her journey inside the city is not charged to anybody.

The airport is a different measurement entirely

Schiphol and the hotels attached to it sit outside the window and are never described as being inside it. That journey is arranged on its own, with the driving time each way written out and accepted by you before the hour is fixed. You know the number before you agree to anything, which is the only sensible way to handle a journey of that length.

Beyond Amsterdam and those airport hotels, nothing is reached at all. That is worth saying plainly because guests occasionally ask about towns further out, and the answer does not change with the length of the booking or the size of the figure.

Using the window well

Be ready at the start of it rather than the end. The clock on your session runs from the booked time, so a guest in the shower at the forty minute mark has spent part of what he paid for. Shower first, put the room in order, and then send the message that fixes the hour.

And if something in the plan changes while the window is running, say so immediately. A room number that was wrong, a lift that turns out to need a card, a decision to move down a floor: each of those is thirty seconds of typing at the time and ten minutes of confusion later. The window is generous enough to absorb almost anything except silence.

One last thing about the clock. The session runs from the hour you booked rather than from the moment of the knock, so being ready at the start of the window costs you nothing at all and being unready at the end of it costs you part of what you paid for. That is the only practical instruction the figure carries, and it is why it appears on every page rather than being buried in a note somewhere.
