I know the struggle to get answers to your questions but meet only people who don't know English. The minimum, basic, English, which is supposed to pe spoken by anyone out there more or less.
But I totally feel you, as sometimes I prefer to write only the good parts of what I see during my trips but also think that this might end up not fully honest. However people are interest about our opinion and experience, so we should do that more often.
Merry Christmas to you and your loved ones! 🎄🎁
