Incall is the arrangement where the client travels to the provider's own premises; this house offers no incall of any kind.
Incall and outcall are the two words that sort every massage listing in a city. Incall means you go to them: a studio, a salon, a private flat kept for the purpose. Outcall means they come to you. Listings abroad often offer both and price them differently, with incall usually the cheaper of the pair because nobody has to travel.
This house does not offer incall. The house keeps no studio and publishes no incall address; the room you are in is the venue. There is no discreet doorbell and no waiting area, and a client who asks where to go is pointed back to his own room. The reasons are practical. A fixed address draws attention, ties the roster to one neighbourhood and makes every client travel, often late, through a city he may not know. A visit to the room he is already in avoids all three.
Buyers who compare figures across sites sometimes set an outcall price beside an incall one and conclude the first is expensive. The comparison is uneven. An outcall fee here already covers the therapist's journey across the city, at any hour, with no supplement for a late night or a weekend. Every therapist profile carries the same rates table, set by the number of therapists and by whether one client or a couple is booking, and the figure shown there is the figure charged.
The distinction also changes how a booking is secured. A salon can let a stranger walk in and pay at the counter, because nobody has travelled for him until he arrives. With outcall, a therapist has already set out before anyone has met the client, which is the plain reason a deposit exists.
Some searchers use incall to mean something closer to "in my room". That is not what the word means in this trade, and the entry for in-room covers that sense. If you are staying in Amsterdam and want a therapist at your hotel or apartment, what you are looking for is outcall, and that is the only format the house sells.
