Hi all! I am still fairly new to hosting, and I am having a frustrating experience right now. I had my place booked for 1 guest today. I set the apartment up for one person and left. This morning after I had set up they requested an additional person come, and I approved it and sent a message letting them know I had not set up the apartment for a second person, and the futon I have does not have sheets ready for it, but if they are not using the futon it should be fine. They message me back after check in time to let me know THREE guests are there (the booking says 2 maximum, three is an additional charge) and that they want to use the futon. I'm extremely frustrated because I was not prepared for this and my apartment is not ready for three guests. They are already there, and I am not able to come and provide additional sheets for the futon. What should I do?
