This is a good place, and I would stay there again. As other people have said, it's small, but it's fine for one person. The toilet, which is shared, is directly across the hallway, and so it's really no farther away than any other toilet would be (just don't close the apartment door behind you if you don't have the key (!!!)). As far as location goes, it is super close to the Eiffel Tower and so also within walking distance of the Arc de Triomphe. Beyond that, I spent most of my time in (and in the areas between) the 10th and 14th arrondissements, which are a little more than a comfortable walk away. But there are two Metro stations nearby, and so getting around from there isn't a problem.
