The parking isn't really free-- everything else about this Airbnb is perfection. All other amenities listed were there, the location is perfect for exploring New Orleans, the beds are super soft and the room is spacious and cool.
The parking is relatively cheap if you find good street parking, or much more expensive using New Orleans parking apps, and while you can technically find free parking, the chance of that is basically nil.
The owners of this Airbnb were very detailed in the information about how to check in and out, and very prompt when we had an issue opening our door (it turned out to be us messing up the lower lock, not any issue with the locking mechanism). They were attentive and helpful and polite.
Most importantly, this is a centrally located apartment which is walking distance from anything you could want to see in the French quarter, and 2 blocks away from the tram and bus stops (for anything you want to see in the rest of New Orleans). If you want to drink and not worry about driving, this is a perfect spot. If you just want to wander around the streets of New Orleans and not end up far from your home, this is the perfect spot. If you want to spend the day in and chill out for a bit, this is a great apartment. What more could you ask for? Free parking? There are more important things.
