I recommend Robert's place. Just as advertise, you have the place to yourself, it's clean and functionnal. Plenty towels provided, and very very soft bed linens. The bed and pillows are comfortable. There is wifi, a TV with basic cable, enough space to move around and keep your (big) luggage. I can't say anything about the kitchen because I didn't use it at all but it is there :) I had a really good stay. Being in Faubourg Marigny makes you feel like you are part of the city. I would say the house is about 20 minutes walk from the French quarter, and the walk there by Chartres st is really lovely. Frenchmen st with bars, restaurants and clubs is nearby. And you can access the Mississippi riverside parc by using the big rusty starcase above the train tracks, just at the bottom of Marigny street. It's the perfect place for a run (or a walk or a picnic), but the neighborhood is really quiet so you can also run in the streets.
If you want to use public transport, the nearest tram stop is on elysian fields / st claude so just 5 minutes away.
I would definitely come back and wish I could have stayed longer :)
