Roberto's place is in a good location- only a few stops away from Frenchman or Canal on public transport. The neighborhood is right on Cailbourne so we choose not to walk around at night. Though the neighborhood looks a little rough the people were very nice to us, and there are security cameras around the neighborhood. Us and our car were fine for the week.
The inside is pretty good for it's price. The AC works great, the door has 3 locks, and there's plenty of towels and bedding. The bathroom is a little worse. Our biggest issue was finding a few roaches (small but still) over our stay. Overall a good price, but I think you're paying for the location and not for the niceness of the place.
Though we never met, Roberto seems very nice and there's lots of helpful info in the apartment provided by him!
