I cannot really relate to the other reviews, so can only tell about the great experience we had with this inn.
We arrived on Friday 5/28 in the afternoon staying for 3 nights and were delighted with the clean room, cozy interior and a firm mattress (which you cannot expect in many European hotels, for instance).
When somebody from the staff put an air conditioner in our window on the following day, I "upgraded" the B & B instantly from 3 stars to 5 stars. I have stayed in many B & B's since 1997, but none of them had a. c.. So we slept even better during our second night and heard no noise although this was Fugawi Regatta weekend and supposedly many drunken sailors in town.
The best part was breakfast. It's in a lovely room downstairs overlooking Bookworks (a bookstore) and Broad Street. We listened to beautiful classical music (an even better selection than on WCRB!) and enjoyed rhubarb muffins.
The staff was always friendly and helpful.
Next time we'll rather come to Nantucket in mid October whenmost of the tourists are gone, but we will definitely return to Le Languedoc Inn!
