The appartment is perfect if you're travelling alone. The appartment is located in a quiet jewish neighbourhood and 3 minutes walking distance from the subway and 15 min walking distance from lots of nice bars in Williamsburg. Therefore I can definetly recommend it!
The appartment itself is old but everything works fine. Only thing that took me a while to figure out was the wifi. The sheets, livingroom, bath room were clean. Just don't expect something flashy and modern. I haven't had any trouble with roaches. So I guess that problem has been solved.
Christiana is good in communication and easy to get in touch with. I'd recommend this appartment to anyone who just needs his/her own space in the evening/at night and plans to be outside and explore NYC.
