Stayed for 2 whole weeks at Judy's apartment as we were in between leases and needed a place to stay without totally breaking the bank. Judy's place fit our criteria of being affordable and safe in New York City. It's not too far from Flushing Main Street where there's plenty of people, and the police patrol around this area quite a bit. Just have the usual common sense and don't go out alone in the middle of the night to dodgy looking streets.
Also, Manhattan isn't really that far away if you get on the express 7 trains (weekday mornings and afternoons/evenings). Even if you have to take a local 7 train, you're almost always guaranteed a seat on the subway, so it'll still be a comfortable ride. Makes more sense to me than paying crazy Airbnb or hotel prices in Manhattan.
Other than that, staying here we had access to all the food options in Flushing, whether it was cheap dumplings or a hotpot restaurant. We never went hungry here, although maybe a detox is needed after all that sinful food.
Judy was also very responsive and extremely helpful. Whenever we needed something, like plates and silverware for example, she'd be right on it to make sure you have everything you need to make your stay comfortable. It was the perfect balance of having a host nearby if we needed something, but we also had all the privacy we needed, with our own private entrance and access to our room. The room was not huge but definitely cozy enough for the price.
If I was a visitor or need a place to stay in NYC temporarily, I'd definitely consider staying at Judy's again.
