In the cities of the northern kingdoms you can find many ladies of easy virtue. Talking with them doesn't guarantee that Geralt will have his needs satisfied. Sex with the prostitutes is available only in specialized locals called brothels. There are two such buildings in Novigrad - they can be recognized by the red lanterns hanging above the main entrance.
There are no separate icons for the brothels - they are marked with either shop or tavern icon. A place well known from Sapkowski's books. It is located in the northern part of Novigrad, few dozen meters northeast from the signpost placed on the bridge of Saint Gregory. Building looks pretty impressive from the outside so it is easy to recognize it.
Passiflora is pretty expensive, but if you play the game the way it is recommended by the main storyline, at this point of the game you shouldn't have trouble with the prices. To use services offered by women in Passiflora, you must first talk to the owner of the place, madame Serenity. You must be pretty clear what you want - available women will be marked on the minimap with heart icons.
Only three girls are available in Passiflora - Viola, Narcissa and Amrynn. Their service costs 40 crowns and is awarded with four experience points.
A brothel with interesting name and rather bad reputation, located near the Novigrad docks signpost. At first glance, the building looks similar to all the others so it is easy to miss it. As usually, red lanterns help with locating the brothel - they hang before the main entrance to the building.
