We stayed as a couple for Mardi Gras and the size and location of this place was perfect for us. It was clean, well furnished and maintained with generous amounts of kitchen utensils, crockery, towels provided. The apartment is within a building accessed via keypad and the communal areas and lift are well maintained which is always an encouraging sign whenever you arrive somewhere new. There's a second keypad on the door. There's no rowdiness within the building so you can relax and sleep as you wish.
The apartment itself is less 7-10 minutes walk of the French Quarter. So you have access to the goings on but can step away from the noise whenever you desire. Also within a few minutes walk are local shops and restaurants. The parades are within 5 mins walk as well
Marigny is a very proactive host and is keen to make sure you have a good stay. Very responsive.
I'd have no hesitation in recommending this place for anyone visiting New Orleans for Mardi Gras or otherwise.
