Steven's place was a great home base while visiting New Orleans for a professional conference. The place itself was very clean and comfortable, and the patio area out back was a really nice feature. I have zero complaints or criticisms, really a great little apartment with everything I needed for my short trip - and it would be plenty comfortable for a longer stay too. There is a lot of stuff within a very short walk if the apartment - the arepas place right across the street being the most outstanding place I tried in the area! The street the place is on turns into Bourbon St. if you follow it far enough.
The place is less than 20 minutes' walk from the Hyatt downtown, where the conference was taking place. Walking there & back did involve going under the route 90 highway overpass. I walked through there several times during my stay, at different times of day including once in the middle of the night (around 2am, walking back from Bourbon St.). Some folks had tents set up under there but I didn't actually see many people - nobody even panhandled me and I never felt unsafe either walking under the highway or in the neighborhood around the apartment. That was my experience as a pretty large/tall dude going around New Orleans. I felt comfortable walking around the area, but others should use their own judgment especially if (like me) they aren't really city people.
