We all know that Rome's public transportation is
BUT, here's the hitch, from what I saw it seems they've removed the Largo Argentina tram stops in both directions. So now the only stop before Piazza Venezia is Piazza Cairoli - which is downright stoopid (yes, with two O's). Let's say you're on the tram and are aiming to take a bus from Largo Argentina, you now have to sprint or lug your suitcases from Piazza Cairoli. Sure it's only 100 meters or so away from the old stop but the the sidewalk to get to the main bus stop is too narrow to accommodate that kind of foot traffic- making it anything but seamless.
A well-designed and well-thought-out transportation network would make it easy for riders to get from one place to another, to change buses/trams/metro without having to jump through too many hoops, without having to sprint through intersections and dodge cars.
What's worse is, apparently now that the tram is situated in Piazza Venezia, there is no chance in hell it will ever reach Termini, like it was initially supposed to (how lovely would it be to have the 8 tram going up Via Nazionale?). Not really a win-win situation, maybe more like a win-lose situation...
