I'm not sure why Ines wrote that the apartment is very small, unless she's used to living in a mega-mansion or a chateau. It's not small at all. In fact, it was originally designed as two spacious one-bedroom apartments and is the entire second floor of a building. If this is small to her, then she would have thought my old apartment in New York was a closet!
As for the room, it has hosted couples before, including my parents, and they found the size of the room suitable. As in any floor-through apartment, parts of it do face the back of my neighbor's house, but it would be a misrepresentation to say that it is "located in the back of a building."
As for her assertions about the safety of the neighborhood at night, you should know that many pathways in Dakar are dark at night because the city always has rolling blackouts. When the power company chooses to give power to our streetlights, then that's not a problem. At any rate, my corner of the neighborhood also maintains several guards who patrol the neighborhood at night. So, it's not really accurate to say that the paths to the apartment "are dangerous during the nights." You just have to be street smart, just as you would have to be in any other part of Dakar.
