While my trip was inadvertently cut short, my stay at Justin's place was lovely.
As other guests have mentioned, yes, you will potentially have to content with thin walls and other guests, but the front bedroom's bed is delightfully comfy, the house is pretty quiet, decorating delightful, and position great for walking or biking into the Quarter. Justin is great at communicating via message and otherwise lets his guests be. Nala is a superb (floofy!) hostess. Check-in and check-out were easy and the directions for getting around clear.
My only extra note would be that if you're prone to environmental allergies, yes, as mentioned, Nala is a very floofy joy, but there's also a lot of blooming plants AND construction going on in the area, so you might want to pack something for sensitive sinuses with that combo and/or double-check the pollen forecast and check with the host ahead of time to see what the state of neighborhood construction is.
