If you don’t get a review after a week or so then gently remind them that reviews are important to you and also to them, as you’ll no doubt be leaving them feedback.
No matter how many sits you do, something you hadn’t thought of before will likely crop up! After 50 sits I had dogs that hadn’t been spayed. I’d always assumed before they would have been spayed/neutered, but no! So that’s a question I now ask.
In answer to your question about finding sit after sit, the key is to save dates and places (I’ve a basic or standard membership so can only save 3) also have joined other platforms as I’m currently housesitting in New Zealand and Australia. I have alerts on the other platforms (like THS’ saved searches) but also check most days. It’s worked so far but, if I have a gap, I do a road trip! It’s fun and I’ve no idea when I’ll stop!
I have no trouble relaxing in a home owner’s home, but when they return it’s always strange which is why I like to leave as soon after they return as possible, although sometimes I’ve had to spend the night.
