Having read this book many years ago, I decided it was time for a re-read since, in the intervening years, I was lucky enough to have spent considerable time in Europe.
Well, this made all the difference, as this book was a joy. Not that it wasn't enjoyable the first time around. It's just that being able to compare one's own impressions with his adds a new dimension. I would have liked to meet Mr. Twain as he had a great sense of humor, right up my alley.
Secondarily, he details some of the mechanics of travel, hotels, tours, etc. such that it places the differences between his age and ours in stark contrast.
Very entertaining!
