I'm a fairly seasoned New Orleans traveller, and have been to the city annually for the past 16 years. We've stayed at the Renaissance Arts for a week both in 2010 and 2012 and I can easily say that it is my favorite NOLA hotel. The roof top pool and hot tub is such a wonderful little oasis, and typically you can have it all to yourself. The staff is always extremely friendly and helpful. Rooms are quiet (which is nice in New Orleans) and very clean.
Warehouse district is a great place to stay with several wonderful restaurants and music venues with in walking distance. Our favorite is Mulates but there are numerous to choose from!
We can't wait to return!
