Interior: In good condition. Only things of notice were some wall damage and the creaky stairs, but the living room and kitchen are quite up to date and modern.
The bathrooms are in good condition as well. The bathtub/shower downstairs is a little high, just as a heads up for vertically challenged people like my girlfriend.
The bed is comfy, but if you get cold easily bring an extra blanket during the colder times of the year. The space heater is helpful to an extent, but being able to insulate yourself will be a better option.
Exterior: It looks like your average Brooklyn neighborhood. A few liquor stores and deli's in the area. My girlfriend and I did learn from a local that the area used to be a bad part of town, but it is improving. I didn't feel unsafe, but just out of precaution we took Uber (about $5) from the subway station to the home at the urging of the local we spoke to.
