We visit New Orleans often and have stayed here several times. The house was lovely before recent renovations, but now it is really exquisite. Our favorite room is the balcony room overlooking the quiet end of Bourbon Street. The location is great - close to the French Quarter plus all the restaurants and nightlife on Frenchmen Street.
John & Dewey are wonderful hosts and go out of their way to make sure your stay is comfortable & enjoyable. I've recommended La Maison Marigny many times, and will continue to do so.
I stay here every time that I'm back in New Orleans. The location's close to everything, but away from the drunks (well, the other drunks, at least).
The owners make you feel that you're staying in their house, and service is outstanding. I'd stay there just for the breakfast, quite honestly. The rooms are furnished perfectly as well.
And finally, the price is competitive, which is great. What else could you ask for?
