This is a basic spot to hole up--generally accurate to pictures, but a bit more dingy in reality, with an awkward layout: the master bedroom is only accessible by walking through another bedroom.
Biggest issue was a strong stench of cleaning chemicals upon arrival that didn't dissipate for a day or two. Not good if you're sensitive to smells.
Minor inconveniences included no body wash or shampoo and handsoap only in the bathroom, not the kitchen.
The master bedroom is exposed to street noise throughout the night--probably better than average for NYC, but if you're not used to street noise, earplugs are a must.
There is a key code for easy access, but the host insisted on meeting up first, which was slightly inconvenient. He also gave us bad parking advice--he was right that you should park on a side street off Flatbush, but he was wrong about the days you have to move your car, so we ended up getting a ticket. Read the signs carefully.
