I have a small (1300ft) Airbnb in upstate NY. I began Airbnb-ing in November 2021.
The aesthetic specifically isn't that important as long as everything is available, clean, comfortable and functional.
I bought some things new, but I also bought things at thrift stores. This is a thing I like to do. You can buy things off of Facebook Marketplace.
Stay in the house for a night or two or have a picky friend stay there. This way you will notice, for example, you need more lamps or a night table.
I think people want parking, internet access (wifi) and cleanliness.
Ask your guests for suggestions about how to improve the house.
I wish I could decorate your house...
