We did the four hour tour. It was two hours in each museum with a lunch break in between. Our amazing guide was Lilyia. She combined the perfect amount of art, history and interesting facts. She was incredibly knowledgeable and passionate. She was always interesting to listen to and moved the tour at a great pace. In four hours you get a great taste of two fabulous but potentially overwhelming museums. You will see the famous ladies like Mona Lisa and Venus de Milo during your tour. But you will leave the tour feeling like you have a greater understanding of how the art work integrated with the history of the times, how it was made and the messages they were trying to convey. Lunch was at a quick inexpensive lunch place. It was a great chance to get to know our guide and fellow travelers. Our tour had only 4 people and was worth every euro. GREAT WAY to experience these museums.
