Kim is a very kind and thoughtful host. I stayed with her for about two weeks. When I arrived, the elevator was broken, and as I use a cane to walk, she helped me with my bags. She was very welcoming, explaining the apartment and checking in on me that first day. The location is really great. As it's in the heart of Harlem, it can definitely get noisy, with folks on the street and cars always going past; but the subway is literally right outside the door, which is great if you're commuting downtown. It's also very close to several grocery stores, little restaurants, and cafés. There's a bus stop right outside the apartment as well, and just a few blocks down is St Nicholas Park, which is a lovely place for a stroll. If you don't like cats, this might not be the place for you, as Charlie is pretty curious and energetic, and often came into my room (which I didn't mind). There's no air conditioning, so if you're staying in the summer it can get pretty hot and humid, but if you're there for more than a few days, this can be easily remedied with a small desk fan.
If accessibility is an issue for you, as it is for me, Kim's place is moderately accessible for someone with limited mobility. It definitely isn't wheelchair accessible, as the only entrance is stairs. However if you use a cane/crutches/etc, there are only about eight stairs in total to get into the building, and there are sturdy railings. There is an elevator in the building to get up to the apartment, but it was broken a few times. The subway stop isn't an accessible one, so if you have issues with stairs, you might want to look into alternative forms of transportation.
All in all, I really enjoyed staying here!
