First off, I Highly recommend staying with Charla. My girlfriend and I stayed there for a weekend and loved it.
Charla herself was super nice and welcoming. She didn't hesitate to give us suggestions on good places to eat or things to do if we asked. She was also very easy to reach and quick to respond to any questions.
She has two adorable rescue dogs, Tillie (Tilly?) and Buzz, who are very playful and sweet. She has it set up where if you don't want to interact with the dogs you won't have to. Tillie did bark a few times in the mornings which might disturb some sleepers like my girlfriend, but I didn't notice at all.
Her house is very cute, and our room and the neighboring bathroom were very clean. As some others have said, the neighborhood does seem a little sketchy at first, but everytime we walked past a neighbor they were very warm. Her house is conveniently just a short ride from the French Quarter and within walking distance from a streetcar stop.
I would definitely stay with Charla again if I were to come back to New Orleans.
