We stayed for more than a week and really enjoyed the place. Everything is as you see on the listing. The check-in instructions are very clear and the host is very responsive in case you need anything. The apartment is conveniently located close to the street car so it's quick and easy to get to city centre and the French quarter. Garden district is also a lovely neighbourhood with good places to eat.
Make sure you read the house rules carefully! As stated there, roaches are indeed common in the city so make sure you keep the kitchen very clean and put away all food. On our first day we left a couple of dirty glasses in the sink overnight and woke up the next morning to a roach swimming in the kitchen sink. After this incident we made sure to wash all dishes immediately and did not encounter any more problems. I don't consider this to be an issue with the place itself, just something to be aware of, as the apartment was otherwise pretty clean :)
