@Sandra7125. Hi Sandra, was the guest's second visit longer than their first or the same? I get the impression if it was that second time around they needed certain things more. If even communication was marked lower second time and you gave the same excellent service then I can sympathise with the difference. No private feedback?
I'm sure I sometimes get 5 stars mostly because the weather was great (guest reviews can be far obscure than we realise). Relax; as a great host you will earn it back 🙂
