@Kippy0 ......Hi Kippy, I have read a lot of questions on this forum but this one is definitely a ‘first’!!
You know it is probably something that many people do on a holiday Kippy, maybe meeting up with the BF on neutral territory and although it may have been embarrassing to you, the guest possibly had no idea she (or they) were audible to the world. She was possibly a very ‘expressive’ person and got carried away in the situation. Guests have no doubt done the same thing in our cottage, we haven’t heard them, but I would expect that it is something that will happen.
I don’t feel it would be wise to crucify her publically in a review if she was a good guest in every other way.
I would just quietly just pull her aside and say something like….”Hey, ****** could not help but hear you last night, no problem as far as my BF and I am concerned but, just thought you may be a bit embarrassed if you knew others could hear”!! And leave it at that.
If she is a reasonable considerate person she will make sure she ‘tempers the tonsils’ next time. If it is repeated then you could possibly make some general comment about …..‘being noisy’
You have to remember when you invite strangers into your home it, to a certain extent, becomes a public space and guests will, in some areas, bring their ‘habits’ with them…..cheers…..Rob
