After an initial few times of agonising over what to say and how, I now use only one guideline in giving reviews: the truth, the whole truth, and nothing but the truth, WITH a measure of kindness that is pressed down, shaken together and running over.
This helped me completely eliminate agony time and is just the fairest thing to guests (chance to reform bad behaviour or to respond in the section below their review once it posts), hosts (chance to make informed guest choices), the community (imagine what would happen if we all spoke plainly but kindly) and to myself (hosting is fun but can be hard work, no need to further complicate matters).
Can I improve and lighten up sometimes? Of course. That's why I take my reviews from guests seriously and always verbally ask them to tell it like it is, as well as put this request in my private comments to them so that they can publicly respond to my review. I'll take the risk of their response going public.
Is it necessary to nitpick over every detail of the truth? Of course not. That's where the grace comes in.
One last thing: almost completely avoid the need for composing delicate reviews by avoiding the "delicate"guest.
How?
One trick that helps me: keeping it real when it comes to pricing, rules and my own profile.
When my price was too low, I attracted undesirable guests who were hard work, while barely turning a profit.
When my rules were too lax, I experienced guests with very different values from mine.
In the community spotlight @Gerry and Rashid mentioned adding more pictures and really filling in your profile well so that you attract similar people; thanks to them for this simply genius suggestion.
For guests who read the details, all this works. (I once had a guest cancel after booking because she couldn't keep one of my rules for which I was very grateful as a problem was solved even before it happened).
For all guests, a truthful review applies.
Happy hosting, thank you for reading, @Annette33 not to dismiss your question at all, I think it is valid, this is only my response.
Peace and love,
Betty
