Stayed here for one night, it was a typical chain hotel experience. Desk staff were mechanical but pleasant and the room was clean and quiet. Nothing to rave about but can't complain about anything either.

Other than my GPS routing me down a dead end street (trouble finding the front entrance)...we had a great family stay here. The bellman helping us was very nice. Easy check in, rooms were spacious and comfortable. The gym/pool were awesome here and we used them. The room had a mini fridge and coffee maker. We did not eat at the hotel as i wasn't paying a ridiculous amount for a NY breakfast. Instead i walked just a few short steps from the hotel over to Panera Bread and brought back some bagels and cream cheese for the family. We did not have time to go to Manhattan but it seemed like it would be an easy hop from here.

Located just 1/2 a mile from the Brooklyn bridge
This hotel is everything the Marriott hotels are all about
Clean nice and perfect for business or pleasure .
Rooms are big and comfortable some have a view of the city
Mostly high floors . The location is near subways that u can get everywhere in the city easily .

We stayed in Brooklyn so my wife could attend the Barbara Streisand concert at the new Barclay's Center. There are not a lot of good hotels to choose from and the Marriott also offered a great location- just a quick walk to the Brooklyn Bridge and Manhattan. That said, when we arrived after a long flight from San Francisco, the bar although "open" was really closed prior to its 12am closing time. New York maybe the city that never sleeps but that does not apply in Brooklyn. That fact, coupled with the snarly service - a blunt "we're closed" left a less than favorable impression.
The concierge also messed up our dinner reservations, although part of it was my fault, they still messed up and were of little help.
On the plus side besides location is the large size rooms, excellent health club/spa services and a professional staff, bar service aside. So I'd probably stay there again just by default, at least until Hilton opens something better.
