We stayed at an AirBnB in Grand Case and loved it. We are planning on staying at the same place in April. It is incredibly common for owners to list their property on AirBnB, Homeaway, or any other site simultaneously so you can get a good sense of the sitaution by reading all of the reviews. Agreed that at this point "AirBnB" is kind of a misnomer as many of the listings are nothing like a B&B or even part of someone's home. Our spot in Grand Case is a 4plex of sorts where the owners rent out all 4 apartments, all of the time. They have one employee who lives in the penthouse apartment and is a caretaker of sorts for the rentals below.

ETA* - said rental in Grand Case is right on the water and more affordable to us / allowing us to stay longer than the Grand Case Hotels, which are beyond lovely but a also beyond our budget. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Joy.gif" alt="" />
