Appain Way. There are 4 or 5 catacombs located on the Appain Way, but we choose the largest San Sebastiano to visit which is said to have contained the remains of several popes and Peter the apostle until they were relocated to St. Peters Basilica. We took the city bus out there which was very reasonable. For the cost of 3 Euros you can ride the bus and metro system all day. Make sure you wear good walking shoes. I wore flip flops and by the end of the day, I had to throw them in the trash because they broke from catching on uneven stone streets all day.
Spagna station where we then proceeded to see the Spanish Steps, The Pantheon, Trevi Fountain (I made sure we threw coins into the fountain to assure a return visit), and the Peoples Square called Popolo. A day in Rome wouldn't be complete without Pizza and Gelato. We found an excellent pizza place located just outside the station exit that does Take-Away. This allows you not to pay the coverage charge of 2 Euros per person to sit down and you can buy the pizza by grams/slice. I had a bianco pizza that was covered with a spicy sausage and potato. So yummy! Then it was back to the main train station to catch our 4:15p train to Milan. The ride takes about 3 hours when you take the fast train the Euro Star. Oh! I forgot! Poor Frank got pooped on by a pigeon. He didn't lean against any buildings for the rest of the trip. Maybe, that was Italy's way of saying welcome.
