Three out of Five Stars
The title alone caught my attention as I passed the travel section at Barnes and Noble. However, the book is more of a historical reference than a travel guide (although the fact Perrottet carted his wife and two young boys with him all over Europe did make for some hilarious moments).
If you're interested in the era of the Borgias, Casanova, and those time periods, you'll probably be interested in the book. Luckily, I read a lot of that sort of thing so many of the references made total sense. Even if you don't, there are a few parts that are particularly interesting -- for one, Perrottet's attempts to get into the Vatican to see the secret bathroom with the dirty pictures on the wall. o_O
Definitely a departure from the average book!
