Lighting in an apartment whose only window is in the bathroom

Shalom, honorable Rabbi. I was asked by an elderly woman who lives alone in a Haredi neighborhood, in a basement apartment that has only a single window, in the bathroom-shower area. Where is it preferable for her to light the Hanukkah candles: at the entrance to the building, at the entrance to the apartment from the outside, or opposite the side with the mezuzah inside the apartment? From the perspective of modesty, and also in order to be able to pray next to the candles during the half hour that the hanukkiyah is burning, she prefers that it be inside the apartment. However, since in that case there is no publicizing of the miracle, and there are no household members present at the lighting, there is a concern that the berachah might be in vain. If so, what is preferable for her? It is not appropriate for a woman to stand and light in the public domain, since this draws attention by its unusual nature, as this is a Haredi neighborhood and it is not customary for women to light by themselves. Also, this woman prefers to conceal the fact that she lives alone, for various reasons such as safety, etc. Thank you very much.

Shalom u-vracha 

She should light in the bathroom window that is visible from the public domain. 

She should first recite the blessings outside the room, and afterwards enter and light.
