Have to admit, we were less than pleased when we had to pay to rent bikes an additional 117.00 after paying 300.00 for a bike tour. Especially after I called Viator and spoke with someone and they told me it would only be additional if I have more than 4 people. That said, We are very happy that we did this tour. It was really worth it. Love that is was just our family. Much easier to negotiate streets, etc, with a small, private group. The monuments were GORGEOUS at night and we felt like we saw everything we wanted to, with less crowds, at our pace. Charlie was very friendly, accommodating and knowledgeable. It was a beautiful breezy evening incredible for AUGUST which made the evening so enjoyable. If you can swing it, I would definitely recommend this tour and this company.
