Karina

Four hands is the format she is asked about often in the afternoon, usually by guests who have done the ordinary version somewhere else. It is 360 euros an hour with a second therapist, and half of that figure is what confirms the booking before either woman leaves. Twenty-five, starting from the centre, which in her case means a short journey, though the window is still quoted at forty to sixty minutes. Latvian, Russian and English are all available to a room. Name her in the first line of a message and the reply says whether that hour is open.

Karina decides which bookings she takes and may decline any of them; she sets the limits for what a session includes, says what they are, and may end a visit at any point, as the terms set out.
