@Greis6 Even numbers are easier to compute. IF your preferred number of guests is 4, then 1-4 pay the same price, 5th & 6th extra guest fee. While you may allow a 7th person and the place may physically support it, perhaps hosting wise it may be easier on you with just 6 to start with. You only have 1 bathroom.
What I would do to get my foot in the door is offer your place at $199 for first 4, $50 for the 5th & 6th. The bunk beds come into play with kids. See how things go and then start adjusting to what you experience.
Love to see a picture of the actual home, to get a feel for the neighborhood.
Nice place, you will do well because of your approach (willing to ask questions). Good luck.
