If the photos indicate that you are renting a large room with large light-filled windows, please know this isn't the case. That photo(s) is of the owners' living space. What YOU are renting is two bedrooms on the lower level, like small hotel rooms but with a small fridge, microwave, table with two chairs, and stocked food/drink. Your bathroom is in the hall, not connected to your room. There is no architectural barrier between you and the owners' living space.
The owners are VERY NICE people, nothing uncomfortable about them. Perhaps they have changed the photos and info by now.
