@Quincy I scored 12 out of 20. Gave myself credit for patio/balcony by having a garden bench in the front garden.
Have no: BBQ grill, washing machine, exercise equipment, hammock, baby gates, coffee maker, indoor fireplace or kitchen (although I have a table & chairs for folks to sit and eat, a refrigerator, microwave, and double sinks for washing dishes). "Kitchen" to me includes a stovetop/oven and cooking utensils. I have a French Press for coffee.
I list a 600 sq. ft. (55.7 sq. m) guest suite, with separate entrance, not an entire home.
I put an unused blender in one of the cupboards - it's maybe been used twice by guests. But looks like it has come in handy for this exercise 😉
