My wife and I spent 3 days touring in Prague. We hired Vaclav Storek, recommended in Rick Steves' book and he was great. We had two days of walking tours in Prague - one of the hill and castle and one of the Charles Bridge and the old town. We also had one day in the countryside at Kutna Hora. Vaclav did a great job, he speaks excellent english and is very knowledgable about the history of the Czech Republic. We learned a lot and had a great time.
