There is a long formal type of contract that I have never had to do with an Airbnb. It wasn’t until I paid (non-refúndable) that I was able to read the content of the contract. It is quite intimidating. They use a noise monitor in the house to determine if your group gets too loud. If security is called you will be charged $200. We were not planning a house party, however, we were having a work get together and our ladies can get a little loud with laughter. We also had to register every person that would enter the property even if they were not spending the night. It was difficult to enjoy our get together worried if we would be reprimanded for noise or if one of our guests brought an unexpected plus one.
With all that being said, it is a third party company that manages the property not the actual owner of the home. The host/company are responsive. They are also accommodating of an early check-in and late check out if it doesn’t conflict with their other reservations.
