One bedroom on the main floor with a full size bed and bathroom adjacent to the bedroom located in the hallway. Bathroom is generally private. The only rare exception would be if I have a personal guest or family member staying in my spare bedroom that is not listed on Airbnb. My goal is not to make my home a hotel full of people so most likely the hallway bathroom will be all yours. The kitchen, livingroom and laundry are shared space that you may use also.
I'm open to as much or as little interaction as you wish. I do enjoy getting to know my guests, but if you prefer privacy, I will totally respect that.
