I'm at the "Hungover" part of this quest where I supposed to find Madame Margot at the local brothel located above the Flotsam Inn. Unfortunately, Margot is NOT there? I paid the peasant at the riverbank for this information. Any help would be very, very appreciated.

Brothel's in the basement.

enter the tavern basement floor look for the door right to the counter in the main hall.
Margot in the first room to the right i belive

Go in the inn
Go down the stairs
Go through the room where the dice players and fighters are.
Behind the bar on the other side of the room is a door. Go through it
On your left will be two floozies, erm, female entertainers, on your right will be another door.
Go through the other door (on your right)

Got it!!! Thanks everyone for your help. I was reading the Game Guide included with the game, it said the brothel was located ABOVE the Flotsam Inn .

Since it was a question, please mark one of the posts above as the answer.

Have fun!
