Multiple rooms in a shared apartment are rented out, so that the common spaces are shared with other people renting through airbnb. Each bedroom has its own additional lock. The space was clean throughout our trip and I always felt safe in my room. For a couple nights while we were staying here, we had some extremely noisy neighbors who used the common spaces a lot. Of course, this isn't a problem with Adeyemi or the apartment, and it was actually quite calm and quite for the rest of our stay.
I felt slightly unsafe walking around the area after dark, but for the most part didn't have any problems. The location is extremely close to two different subway lines which made transportation extremely easy.
