Outcall is the service that comes to the guest's own room instead of asking the guest to go anywhere; it is the only way this house works.
The word belongs to the trade rather than to hotels, and it describes a direction. In an outcall arrangement the therapist is the one who travels; the guest remains in the room taken for the stay. Its counterpart, incall, would send the guest out to an address of the provider's choosing. This house has never kept such an address. There is no studio, no salon floor and no discreet side entrance anywhere in the city, and so every reservation, whatever its length or format, is an outcall by construction.
A traveller who has paid for a room with a view of the Amstel, or a suite high above the Zuidas, has already chosen the setting for the evening. Outcall respects that choice. The guest does not dress again, does not summon a car, does not cross a lobby twice. The only movement through the building is hers, and it is brief.
It also removes a question of taste. A visitor to Amsterdam cannot easily judge an unfamiliar premises from a photograph, whereas the room upstairs was chosen with care and needs no judging at all.
All of central Amsterdam lies inside the service, from the canal ring and the museum quarter to the conference hotels around the RAI and the business district in the south. Forty-five therapists cover it at every hour of every day of the year. Schiphol and the hotels along the airport road are taken by arrangement. Nothing beyond the city is served; a room reserved in a neighbouring town is out of reach, however short the drive appears on a map.
Distance never raises the fee. The figure on the price page holds for a room within sight of the Rijksmuseum and for a tower room out by the orbital motorway, and neither a Sunday nor two in the morning adds a cent to it. The hotel zones entry describes the parts of the city most guests write from, and the arrival window entry explains the timing.
