What is the best city tour to see Trevi Fountain, Piazza Navonna, Spanish Steps, Pantheon...that's not too expensive?
Walks of Italy offers a daily 5:00 pm tour that covers exactly those sites, designed as sort of a welcome to Rome twilight tour. 2.5 hours long. Maximum 12 people, excellent guides, can offer general guidance about Rome. Even includes a gelato at this amazing gelateria with 150 flavors to choose from, about 15 different types of chocolate as I remember. List price is 29 euros, but I believe they offer senior discounts and also a 10 percent discount to readers of Rick Steves books. I can't compare it to other similar tours, but I can recommend it.
