@Simon3254,
Typically, a reservation will have the nightly rate (including a discount, if applicable), the customer service fee which is assessed by Airbnb Service and goes directly to them, any taxes that are required by the property's local municipality, and a host may add a cleaning fee and pet fee.
Unlike a hotel, most short-term rentals do not have full-time cleaning staff that allows them to average a cleaning cost to the nightly rate. Cleaning a STR after a two night stay will cost the same as for a week or longer stay, and often the money goes directly to the cleaner. The additional cleaning fee is less impactful for a longer stay than a short stay. For example, if a host charges a $70 cleaning fee, that's an additional $35 per night for a two night stay. However, if the stay is two weeks long, it's only an additional $5 per night. Ultimately, you have to determine if the total cost of the stay fits within your budget regardless of how the fees are applied.
