We spent a three hour walking tour with our charming tour guide, Peter who met us at our hotel first thing Sunday morning. Peter, a very approachable and laid back person, definitely knew his history. It was a delight to learn all about Vienna with this extremely knowledgeable guide. You can tell, that he LOVES Vienna. WE felt like we definitely received our money's worth and would highly recommend Peter to others. I only wish we could have spent more time with Peter to explore the countryside. That will have just have to wait for our next visit. Thanks Peter!
