Question about house sitting

I'm a pet owner looking for advice on how to keep a rover sitter comfortable 🙂

I've used rover a few times for my dog and two cats while away, and in the past have just done a few drop ins a day. My dog is getting elderly and needs more potty breaks, so we're thinking of trying house sitting when we're gone for a week later this summer!

We have a smaller house and no guest room. We do have an air mattress, but also wondering if it would be weird to offer our primary bedroom as an option as well? Obv with clean... Everything on it. I assume they don't want to sleep in my kids room. I just want to make sure they are comfortable and happy, whatever that may be!

Also if you have any advice or words of wisdom for a fit time person hosting a house sitter I'm all ears.
