Clean hotel, good location, needs a little updating
We stayed at this Marriott for 3 nights. Check in was quick. Although the rooms need a bit of updating (dated decor, bed spread, wallpaper...), our room was very clean, large and we had a lot of space to put our luggage. A big bonus was the complimentary free Wi-Fi service throughout the hotel.
The3 hotel is situated in a pretty good location. There is a Duane Reade drug store next door (snacks, water, travelling essentials...). There are many restaurants nearby. We walked everywhere (but then again, we walk quite a bit). The Rockefeller is just 4 blocks away, and it's a 15 minute walk to get to Central Park. For those that don't enjoy walking, the subway is just 1 block outside the door (Lexington). 
We enjoyed the free coffee offered every morning. We would then head to the Ess-a-bagel for breakfast (cappuccino and a bagel with flavored cream cheese) before sight seeing. The Ess-a-bagel is just one block or two across the street from the hotel. 
The concierge was most helpful and recommended really great restaurants for dinner based on our mood for that evening (fine dining, pizza, burgers...). He was more than helpful, pleasant and knowledgeable. He really impressed me. 
Parking was expensive ! However, it's valet parking and we didn't want to drive around in the madness to look for a cheaper parking garage.
