This is a great small-feel hotel. If you want a large "grand" hotel go to the Monteleone. If you want a more intimate experience, Mazarin is a good choice. It's close enough to Bourbon to have some noise, but you're not in the thick of it, and you can certainly escape from the Daytona Beach-ness of Bourbon here.
The rooms were very nice - nothing too crazy, but well-appointed and -maintained, and the bed was very comfortable. The courtyard is beautiful - a nice place to start the day with the included breakfast. Speaking of which, this was perhaps the biggest let-down. With the quality of food throughout the city, I would suggest the hotel step up the baked goods which were dry and not up to the standards of the rest of the hotel.
The front desk staff were very gracious and accommodating - especially Ulises, Rene and Manny. They made sure we were well cared-for.
All in all, a very nice place.
