We have not stayed in a hotel in many years so I too know B&Bs as we they are our first choice when traveling. Last year we added AirBnB to our options when we traveled over 5 months staying exclusively in B&B and AirBnB accommodations in the South. Of the 14 places we stayed, many of our stays were for extended periods or repeats of places we stayed earlier, only one was a gay couple. They were not flamboyant nor intrusive in any way. The other people staying at the house were varied in backgrounds but shared an interest in history so conversations at breakfast and tea was lively and educational. Actually each of the hosts at every place we stayed was friendly and offered something positive to our travel experience.
My husband and I close on our own B&B property in a couple weeks. I hope we are able to provide our guests a comfortable, relaxing stay with great food and stimulating conversations at the breakfast table, just as we have experienced on our stays with others.
Well, good luck to you!!
