Extra Fee? Guest informs me via the app after one night that her boyfriend surprised her

[Sofia496]

Hello everybody!

I am new to hosting. I don't have any reviews yet for my current listing. I have a guest who booked for 5 nights. One night passed and she informs me via the app that her boyfriend surprised her and there will be two people living in the apartment now. The boyfriend will stay for four nights.

I rent the entire apartment which accomodates four guests. She booked the apartment for one person only.

I have changed the listing multiple times since she booked adding new rules and increasing the cleaning fee and adding extra charge for extra people. 

What is the process for claiming an extra fee, since an undocumented person arrives? Is the money worth to maybe get a worse review?

@Sofia496 I would recommend that the owner have a look through this very forum to get a sense of what the more common issues are in Airbnb hosting, rather than fixate on a highly specific and unlikely incident. 

Solo guests aren't an ideal target market for a large Entire Home listing, but fine for Private Rooms with onsite hosts.

Thank you very much Andrew for replying. The owner is only 55 but she finds it difficult to go on the internet. Honestly, the toughest part of hosting this listing is explaining her everything. I need a new approach and what you said gave me an idea about how to approach this matter. Thanks.
