That looks like a comprehensive excel work! well done!
It appears that airbnb hosts spent lots of time interacting with guests (booking, welcome, post stay, solicit review, etc). Imagine hosts with multiple properties, always on the go while still need to provide timely response to guests.
We baked up a simple mobile app: The essential feature is to send emails (welcome, thank you and solicit review). The tool takes only a few minutes to setup (using AirBnB property and user id)
Perhaps we can help to implement some of your Excel spreadsheet for you at no cost in a mobile app that further simplify your work, leveraging mobile functionality (on the go, guest interaction, tracking, multiple properties management, multiple rooms, pricing, earning, etc)
Our current app is fairly simple and it’sin beta. We would love to get your feedback on how to make the app more useful to hosts like yourself. iOS only for now (search Appstore for Superhost by BonGEO, Inc)
Thanks in advance,
