If you’re interested in literature as well as travel, can I recommend “Abroad: British Literary Travelling Between the Wars” by Paul Fussell? Beautifully written and knowledgeable book.
So many writers between the wars lived abroad - D H Lawrence in Sardinia and Mexico, James Joyce in Switzerland and Italy, W H Auden in Brooklyn New York (I accidentally came across a plaque wondering around when I visited). And so on.
Advising a friend on the merits of buying a property abroad, the much travelled D H Lawrence tries to dissuade him: “Don’t have any ideas about places, just because you’re not in them. All places are rough and terrestrial”.
