We had a fantastic stay - Sonder was super easy to book through, and their app is very helpful. They're polite, accommodating and communicative.
The location is within a half mile of all the prime spots, just outside French Quarter. It's got a super nice design/layout, and we especially liked the record player.
The only issue was that the check in was quite late (4pm), and we needed to store our luggage during the day (at a place Sonder recommended that was very inexpensive).
