Billy's place is exactly as described in his listing: stylish and convenient, with readily available free parking on the street. My only caveat would be that the seating in the front room, though lovely, is very low and might be difficult for older guests, particularly those who have knee, hip, or back problems.
Billy himself was delightful; his responses were prompt, and he was very responsive to the one issue we had, which was water leaking in through the back door. To be fair, it was a monsoon, so I'm not sure any door could have withstood the attack without a few drips.
We would definitely stay here again if we come back to New Orleans.
