This is an absolutely wonderful house. When we booked we were expecting to have 6 or 7 people in our party, but a couple couldn't make it so there were just 4 of us. So it was probably a little crazy to have this much house for just 4, but we loved every minute of it. We each had our own corner with the perfect bedroom to suit our needs, and then congregated in the living room, kitchen or back patio for meals and conversation. Our excursions into the city were hit or miss, given the crowds, etc, but we all agreed the time at the house was the highlight of our trip.
There were a couple very minor housekeeping issues when we checked in, but small enough that we didn't even mention to the property manager.
This place is very secluded, and there's not a lot going on in Slidell - although a 24 hour grocery and plenty of fast food options are nearby. If your goal is getting to and from New Orleans, definitely rent a car. It was a $65 Uber from the airport, and on a busy weekend like Mardi Gras it would be $100+ from the French Quarter. We drove down to City Park in NOLA, left the cars, and did Uber from there which was only about $25. One night I also took a drive over to Biloxi to check out the big Gulf Coast casinos, and it was an easy 50-min drive.
Overall, if you don't mind being away from the action, this might be the best option out there.
