I’ve been the first THS sitter for a few newbie hosts, in the U.S. and U.K. I flew to all of those sits. They were all gracious and whatever minor issues I had, I dealt with them. They all gave me five-star reviews and I did likewise.
Note: I give factual reviews and don’t gloss over, unlike some sitters. I knock down stars for anything significant.
When any host gets a good review from me, it’s credible.
One pair of the newbie hosts were the most hospitable of all my 18 sits, by far: Who's on a house sit now? How's it going? - #2648 by Maggie8K
I screen hosts carefully to make sure we have a strong mutual match.
