If you're trying to get to midtown Manhattan, you want to take the Marriott shuttle to LaGuardia, then take the Q70 to the MTA stop. You'll need to take the E line, 6 stops. 1-1.5 hr trip.
Overall it’s an OK hotel. Kind of run down but the staff is nice and the rooms are clean. However, it is HOT in this hotel. It’s got to be over 80 degrees in the lobby and bar. The rooms are hot too.
Probably the closest hotel to the LGA terminal. Walkable if necessary. Typical Marriott furnishings and decor. Mattress lopsided & worn. Room AC didn't seem to cool room very well.
