What a cool place!
Here's something very important to note: EVERY ROOM IS DIFFERENT! We were in a group with 3 couples, each with their own room. I saw all 3, plus a selection of a few others (The staff let us go check out rooms to decide which one we liked)! All the rooms were the same price, but they were all VERY different. Some were huge, some were very small. Some had jacuzzi tubs, some did not. Some had balconies, some had views, some had windows. Some had very high, vaulted ceilings, and the rooms across the way in the carriage house had brick walls. We ended up choosing a room with 2 double beds on the 3rd floor, overlooking Dauphine street. We had a balcony, but there was no door, just a very heavy window that opened onto it, but once the window was up, it started sliding down again...so I decided that it wasn't worth twisting myself into a pretzel to go out there. But it was still a cool room. The beds were SOOOO COMFORTABLE! I'm a very low-mainteance traveler, but I'm a VERY picky sleeper. These beds were almost as good as mine at home! My parents, who had another room, said the same thing. The other thing I was worried about was the balcony facing Dauphine (and Bourbon St a block away). We did have have some noise, mostly drunks walking down the street and yelling about fighting each other, and the lovely car-horn battles. But it wasn't too bad, I still got plenty of sleep, and I imagine we had one of the louder rooms, as most of the rooms don't face that way.
The free breakfast was pretty good, as hotel breakfasts go. The pool/courtyard was really pretty, but people were always out there smoking, so I didn't hang out there. The bar, May Baily's, is small and cute (complete with history!), but also smells of smoke, if that type of thing bothers you like it does me! It's pretty funny that people say it's "haunted," I imagine everywhere in the French Quarter has a similar claim! I love ghost stories, despite the fact that I think they're full of crap, but I didn't hear any good ones here.
The staff were awesome. The maids were always friendly and said good morning to you on your way down the hall, the parking attendants were super friendly and informative on your way in and out of the hotel, and the front desk staff were great. One lady, her name is actually Betty White, no joke, knew us by name by the end of the trip, because we talked to her so much and got all kinds of stories and recommendations from her.
As has been said, the location was great, and we walked everywhere. It's $30 a night to park here, and your car will be worthless in the French Quarter, so if you're staying a few days, do what we did: turn in the rental car early! You won't need it! The parking attendants were great with getting taxi's so all of our group could get to the airport at the right time.
