I have this map of Phlan:
It does not list Madame Freona's Tea Kettle, however. In Defiance in Phlan, it only describes the Tea Kettle as follows:
Madame Freona’s Tea Kettle (and Freona herself) is a mystery to many. In the tumultuous Phlan, this is a place where people can go to have a drink or meal and escape the tensions of the schemers and the power-hungry. With the Tea Kettle’s reputation as a haven, adventures who can be discreet and behave themselves can often find employment there.
Is there a designated location for the Tea Kettle, or is it up to the DM to place it somewhere?
