Looking for reasonably priced accomodation for four for a few days in February
Place d'Armes Hotel, historic hotel half a block from Jackson Square.
I would avoid the French Quarter and go for an AirBnB in Marigny or Bywater. Both are a short walk to FQ, but even closer to the famous Frenchman St for live music, restaurants and nightlife and both those neighborhoods are filled with young, hip people and the places they hang. That way you get easy access to everything but can avoid the huge, conference hotels and mayhem of the FQ. But check out Provenance's new boutique hotel (coming 2015) The Old No. 77 Hotel & Chandleryin the Central Business District. Haven't been, but it just opened and that hood is right next to FQ.

There are a lot of great hotels in the French Quarter. I would check out Hotwire or Priceline Express Deals to see what you can come up with. Both allow you to chose a specific section of the city where you want to stay, and even though you won't see which hotel you got until after your purchase, you will be able to see the star level and customer reviews beforehand.
One thing to be aware of when picking a hotel in the French Quarter is parking charges. What some of these hotels charge is nothing short of criminal. Take a look at a company called Premium Parking. They operate a number of parking lots/garages in New Orleans. You may have to walk a few blocks to your hotel, but it's worth it for what you'll save. You can still do this if you use Hotwire or Priceline. Once you find out what hotel you got, go to their website to see how much they charge for parking, then compare it to Premium Parking.
The The Westin New Orleans Canal Place is nice and usually has reasonable rates. It is on the edge of the French Quarter and right next to Audubon Aquarium of the Americas. Just a short walk away is the Davenport Lounge which is awesome. Also, across the street is Harrah's Casino. If you stay in a hotel right in the middle of the quarter like the Royal Sonesta Hotel New Orleans or Hotel Monteleone it will likely be much more expensive. One other plus about the Westin is its proximity to the river. Let me know if you need restaurant recommendations. Mardi Gras falls early this next year, February 17th, and I would suggestion not coming during that time if you want to really experience the city.

Best Western Plus St. Christopher Hotel by the French Quarter. Great price and on the outside of the Quarter so its close to everything but less noise at night so you can sleep.
check out vrbo or air bnb. There are some cool, affordable places to stay in safe places. Lots of value there
