Catherine's place is excellent. It's beautiful inside with comfy beds and plenty of space to spread out. There's even an outdoor space if you're so inclined and the A/C works great if you're there in the summer.
The place couldn't be better located - a block from Frenchmen, two blocks from the French Quarter, 20 minute walk to downtown, and 10 minutes to the Bywater. Oh, it's also next door to R Bar, one of New Orleans' best bars.
The hosts are excellent as well - communicative, kind, and thoughtful. They even put a Sazerac--a classic New Orleans cocktail--making kit in the apartment.
Overall, we loved it, 10/10, highly recommend.
