My wife and I just spent 3 days with Rich Brunn of Rome Day Tours. For anyone who is thinking of a walking tour in Rome, we recommend Rich. Aside from getting us past lines at the Colleseum, and the Vatican, Rich provided so much information in a clear, concise and down to earth manner our visit to this fantastic city will be remembered for years to come! You can email him at firstname.lastname@example.org. If you have a Comcast account it would be be better to use a different email account such as gmail, Comcast can be weird with European emails. Ciao!
