The apartment was exactly as described. Instructions for entry were clear, and the apartment was ready a few hours before check-in time. It's in the back of the building, so even though the streetcar was quite loud from the street, we never heard it inside the apartment.
This is a great location if you want to be able to walk to all of the various amenities downtown (French Quarter, Warehouse District, and CBD all within walking distance). It's a bit trickier if you have a car, like we did, but there are two garages within a block of the apartment. Neither one is cheap, but assuming you're not constantly coming and going, it's still cheaper than valet service would be at a hotel.
Check-out instructions were simple and reasonable.
