The Good: location is amazing. Perfect for Williamsburg.
The Bad: the L train line passes very close to the apartment causing noise and vibrations every 3-20min 24h a day everyday.
The smoke detector was removed.
The apartment owner requests that you leave an annoyingly bright fluorescent pink bulb on all the time (for plant growth).
There are no curtains or shades anywhere in the apartment so at 6:30am expect to be woken up at sunrise.
If you want to get any good sleep I do not recommend this apartment (even with air plugs and a night mask).
