Noisy
The location is convenient to a lot of what one might want to do in Memphis. The decor is pleasant and well maintained. The bed was comfortable (but the pillows are either insubstantial fluff or bouncy bags of shredded foam -- there wasn't a really good firm pillow on the bed).
Our room was far too noisy. It had a connecting door to a stranger's room, and we could hear their TV clearly enough to follow the show they were watching, as well as their conversation. There was also noise from the hallway, and light coming into the room from under the doors to the hallway and the other room. The blackout drapes were routed into a corner and didn't close that corner gap all the way -- we had to pull them across the desk chair and try to block the light that way. (This room faced east, so we got a ton of bright sun the first morning, and more light than we wanted the second morning since we couldn't eliminate the gap.)
The in-room WiFi is free and easy to access. The parking lot is valet-service only, which seems inconvenient ($22/day). On Saturday afternoon I just parked on the street rather than subject myself to waiting for the valets. 
I love the citrus-scented shampoo that Marriott uses, but that's not enough to compensate for the other shortcomings. For the money they charge, this room was very disappointing.
