If you are based in LGA, I would advise you to get a room for rent near LGA close to Vaughn College of Aeronautics in East Elmhurst. It's literally walking distance to LGA. It's a safe neighborhood with plenty of food options on Astoria Boulevard. The neighborhood of Astoria is not bad either but way overpriced plus you will need to take a bus to LGA instead of just walking there. Hope this helps,
