Possibly if you meant Hemingway would be repulsed by the Islamic suburban areas, though he might have liked the exotic nature of them. I too have been to many old European cities and then recently read some about his time in Paris. Central heat would have been a luxury to him. Cold water limted heat flats did in fact exist in large cities even in the US at least through WWII. So I still say be careful about projecting modern views back to the early 20th century. Life was much rougher then with only the rich having central heat etc.
No need for such a warning, as I have never done this. You appear to be reading considerably more into my words than what I actually stated.
