It's relatively close to Kenner and if he uses Jefferson Hwy or Airline to get to Kenner in the mornings, it would be against the flow of normal traffic and it would only take 10-15 minutes. The Garden District is nice, clean and relatively safe. Not to mention there are a ton of really great bars, restaurants, parks, museums and events to take in. Rent will probably be higher than in Kenner proper, but it might be worth a little bit extra to live in a nicer neighborhood. Even if he's on the road alot, it would be fun to live in the Garden District on the weekends. Lot's to do and see.
What ever he does, tell him NOT to entertain living on the West Bank. Don't. Do. It.
