We stayed for one night while passing through New Orleans. The location is super convenient as it is only 8 blocks to Jackson Square and one block to Bourbon street. Parking is $38/day. Of all the Courtyard Marriotts we've stayed at, this one was the best in term of décor, cleanliness, and amenities.
However, we heard quite a lot of street noise, even on a high floor. The aircon system blower was very loud, which would normally be a downside, but we were able to run the system all night to drown out the street noise.
