Well this place may seem out of the way, it is a short walk to Vatican City, it's a block to a train station which is also the starting point of the main bus line which tourists take (64). Other buses are a short walk in the other direction. This makes it easy to get almost anywhere in Rome. The local train station can take you to the main train terminal in about 20 minutes for 1.5 euros. It is on the fifth floor , which gives a lovely view of St Peter's Basilica dome. There is an elevator in the building.
