I had read all the recent reviews on tripadvisor (my hotel bible).
I found it more mixed than I had hoped.

Pluses:
Good size, quiet two-room suite. It was reasonably priced with excellent valet car service. There was a good kitchenette as a bonus. The top floor gave no problems with noise.

Minuses:
I had asked a crib be put in the room twice before we came. When I had to call from the room and ask the third time, the front desk said "Oh, would you like a crib in the suite?". Then I felt like a tip was expected for the 30 seconds it took to assemble. (I generally tip well, but didn't like that I had to ask 3 times).
There was only one temperature control which would have been fine if I had known. The living room and the bedroom were somewhat different and I got up in the middle of night searching for an extra blanket. The linnens and pillows were disappointing too...5 pillows, but all the same - quite uncomfortable.

Have to agree...this is a super place to stay, especially on business. The breakfast & the gym are very nice and security is pretty tight. Staff is friendly. Try to get a corner room on a high floor. Overall, very comfortable and good location.

I stayed here with my parents while visiting my brother over a weekend in January. The location is good and the staff are acommodating- we had an issue with our reservation and the staff took our word for it, even though it was possibly our mis-understanding.

Our suite faced Light Street, and it is noisy. I'd recommend getting a high floor and asking to stay off of Light and off of Redwood

Breakfasts were crowded, but food continued to be brought out.

Other observations:
- for the "One Bedroom Suite", the bathroom is in the bedroom and not directly accessible for the person staying in the living area on the pull-out sofa.

-The suite is smallish- you have to move all of the furniture in order to pull out the bed.

-Walls are thin- I had to call security due to a loud group of people in the suite next to me.

-We did our own parking in a garage a block away (entrance on Charles St)

We came from Philly to stay overnight and go to the Aquarium. The room was sparkling clean and we were allowed early check-in at 1pm. As always, Marriotts are always beyond expectation, and we had a great stay. There are no fancy views, but the kitchen was great and the bed really comfortable.
