We had two private tours with What A Life - the Sistine Chapel and Vatican and the Colosseum and Forum. Both of our tour guides were amazing and the experiences were fantastic. We went straight for the Sistine Chapel in the morning and got to experience it with only about a dozen other people there; a total treat. And my 7 year old twins were well accommodated on our Colosseum tour; our guide patiently answered all their questions and they loved the experience. I didn't get a single cry of "I'm bored." I would recommend What a Life Tours very highly for anyone coming to Rome.
