Staying at Greg and Margie's place was great. Its hard to tell from the map alone but the location is perfect if you're looking for a quiet place with easy access to all of the best parts of the city.
It's only two short blocks from St Charles, the major thoroughfare through town that has a streetcar to take you into downtown and the French Quarter. The streetcar operates 24 hours a day and comes every ten minutes for the most part. Also, if you're not looking for a crazy night out on Bourbon there's Magazine Street about fifteen minutes walk away with tons of shops, restaurants, and great bars.
The accommodations are exactly as advertised if not better. The separate entrance to the room and bathroom is fantastic and really convenient. I'm a frequent visitor of New Orleans and think this is a great place to stay.
