To add a little More--

        Twain certainly enjoyed Florence.  He strengthened his
friendship with William James in the 1892-93 period while both men had
their families on vacation in Florence.  James wrote to a couple of his
friends that Twain enjoyed the dinner parties with his friends
immensely, and that he provided the spark for conversation and song.  No
surprise here, I guess.  Just imagine a dinner or party with Twain.
