The reviews you've read about Bon Maison are quite accurate. My partner and I stayed in unit B - the closest room to the main gate - and, gulp . . . . Bourbon Street.
If you're intent to hang out in your room and watch TV at night, this isn't the best room choice - stay in one of the courtyard rooms, as the noice from the street may be a bit much.
If you're intent on going out and enjoying all the sites, sounds and tastes of this cultural gem of a city, then Unit B will be just fine.
You're heard the phrase, "location, location, location," well, you've hit nirvana at Bon Maison. You're close to everything one could hope for . . . . bars, restaurants, historical sites, etc. without being stuck in the middle of the noise and distractions. Chuck's Bon Maison is located on the quiter end of Bourbons Street - the beginning of the residential section.
Chuck runs a very efficient and accomodating Inn - and the price, by New Orleans standards, is quite reasonable.
If you want clean accomodations with historical charm, then Bon Maison Guest House is the place to be . . . . . If you want "cookie cutter," and predictble without much charm - stay at The Holiday Inn or Marriot.
