Depends on where exactly the coop is! Unfortunately the area is going a little down hill, especially since Eric Gioia (D) allowed new licenses for street vendors - now the place is over run by kebab stands and halal meat vendors - that's not too bad during the day - but at night between the deliveries of off the truck meat, the amount of street garbage and the noise is not what I'd call ideal! If she's going ahead with buying - ensure that the co-op is in the back of the building (if she buys in the front of the building on the top floor or the 1st floor - the noise will be the same - back is better!) , off any main road/street. I used to love Jackson Heights - but the noise pollution has become too intense - that's my 2 cents - good luck with the search!
