Long Island City is so close to Manhattan, it's worth it to stay here to save money. Area is little gritty looking but is perfectly safe. Plenty of car/pedestrian traffic up to 9:00 pm on a weekday. I never felt unsafe walking back to the hotel at night. There is a 7-11 next door. It's a 5 min walk to the 33rd St station on the 7 train, and it's 5 stops to Grand Central.
The rooms are clean, but the furniture/fixtures are beat up. Toilet handle was loose (missing the retaining nut). The switch on one of the wall lamps was loose (again, missing a retaining nut). Guests really bang things up. Still, these little things should be fixed. My wardrobe closet had the door removed. Probably broken by a guest. The fridge in the room is big, which is nice, so you can store larger bottles of water/soda standing up.
The toilet in the bathroom is extremely low flow. I swear, it seems like it doesn't flush more than a quart of water. But it works, much to my surprise.
The continental breakfast is basic, but it's pretty decent way to start your day--eggs, sausage, juice, coffee, bread/rolls, cereal, yogurt.
