What is the author's tone in Iberia: Spanish Travels and Reflections by James A. Michener?

Michener is reporting to the reader everything that he experienced in Spain. However, since the book is a first hand experience about the writers travels through Spain, it is full of his own biases towards the things that he loves. He does include things that he doesnt like as well, like Gothic architecture which is a very important component to Spain. The tone of the book makes it a quick read, though it is well over 900 pages. The sentences flow along very well and it is overall an easy read which will make the reader want to go to Spain to have his or her own experiences. The flow of the book has no relation to the way that it is divided and almost reads as one chapter because of how much he jumps around. It is almost as if it is written as a letter to a friend, without ever personally addressing a person.
