I spent several years living in Europe in the early 1990, mostly Germany, but also Italy and Portugal.
The German summers without A/C weren’t all that bad, but one hotel I spent several months at had no screens so you had a choice between sweating all night or waking up covered with mosquito bites. Got the the point where I made a count of new bites every morning - record was 29. Eventually one of my German colleagues showed me their trick - a wall plug in insect fogger. That worked more or less, along with flypaper.
Italy was worse in the summer as the heat lasted longer and 90F days were not uncommon.
One interesting thing I remember well about Italy were the roadside prostitutes - they were on high seats, with a beach type umbrella, overall very similar to a beach lifeguard arrangement. The ones I saw were all black women, probably from Italian speaking parts of Africa. When I asked about it, I was told that their primary clientele were truck drivers... this was on a relatively rural two-lane highway 5 or so miles outside a town with a population of perhaps 25K people. In any event, never saw anything like that in my European travels.
During that `hot’ summer of 1983 they installed screens (”Fliegerketten”) on the windows of our quarters. The German workers installing them thought these uniquely American since their homes had lace curtains for that purpose.
Like the lace curtain window in “Blazing Saddles” as Lili von Schtupp was moaning, “It’s twue...it’s twue...it’s twue!”
Around Naples in the late 60’s we called the roadside prostitutes (all of whom were white) “Campfire Girls” since in the winter months they would gather around a 55 gal. drum with a fire in it.
