The hosts: I shared the 3-bedroom apartment with four other people and two dogs. I had my own room, but the bathroom was shared with two people. Roommates seemed perfectly nice.
Noise: The building has extremely thin walls, so you can hear everything that is happening not only within the apartment, but also on the floors above. This causes some inconvenience as the roommates stay up quite late watching TV, and the building is generally quite noisy. You can also hear the subway, as it runs above ground in this part of town.
Cleanliness: the kitchen was usually clean, but the bathroom was not very clean. because the roommate smoke in the apartment every evening, there is a strong smell in the common areas as well. There was also generally quite a lot of fur all over the house because of the dogs.
Location: apartment is a 5 min walk from the Myrtle-Broadway J/M subway lines
