@Naima58 If by recommemded base fee you mean Airbnb's "price tips", pay no attention to those at all. They are insultingly, absurdly low and most hosts can and do easily charge far more than that, even double, no problem.
What you have to understand is that the price tips are for Airbnb's benefit, not yours. The company doesn't care if you don't make any profit at all. They care about bookings coming in so they can collect their service fees, which is their primary source of income.
So check out what other Airbnbs in your area, which are similar in terms of size, maximum number of guests, amenities offered, etc, to arrive at what seems reasonable. And of course you have to keep track of your expenses. Don't race to the monetary bottom to try to attract guests. Value what you are offering- its really nice.
Perhaps it's how most rentals work in your area, but it's rather unusual in my experience, for an Airbnb to come with an employee who the guests can just ask to do anything they want. I think you should define what he does as part of the booking fee and have clearly stated charges for anything beyond that, or some guests might treat him like their personal servant and have him running around all day doing their bidding.
