I had a group of 17 people stay at Mia's place for a Bachelorette party. It was pretty much perfect for what we needed! It's about a 15 minute drive to the French Quarter, but Magazine Street is also within walking distance, which has lots of fun restaurants, bars, and shops. The house is a duplex that has been joined together, so it has kind of a U shape (you have to walk all the way to the back of the house to get to the other side). It was plenty of space for all 17 of us, but just three bathrooms, so keep that in mind if you have a big group renting the whole house!
I will say that a few areas around the house (away from Magazine Street) didn't feel super safe, but you just have to be smart. And the house felt very secure, with a gate code and door code entry to get into the house.
For a big group like we had, it was very affordable and very convenient. It was super clean and had tons of towels and linens, which we appreciated. Mia even helped ship my friend a dress she'd left in the closet, which was really nice. We had a great experience overall. Thanks, Mia!
