Too lazy to walk around Rome’s huge city center? Sitting on the open deck of a sightseeing bus will sound like an tempting alternative to tiring strolls. You’ll find many different double-decker hop-on hop-off buses, here. The 110, run by the public transport company, is the cheapest solution. All the other sightseeing buses are private. Most show you downtown Rome’s main landmarks but some offer alternative tours: either outside the city-center (such as Appia Antica Park) or devoted to specialized routes (Christian monuments and churches).
