I am still short of time to contribute to this community as I would like to, but now I write just a few lines about Leonardo Express, the shuttle train that goes from the airport into the town center in Rome, in the Termini Railways Station.
I am not going to write about timetable, cost and how it compares to taxis, I am just writing to say something very simple to Japanese/foreign people that take it: "DON'T TO GET DISCOURAGED OR DEPRESSED BY WHAT YOU SEE in the 40 minutes travel, the rest of Rome is not that ugly".
Last week returning from Las Vegas I took the Leonardo Express practically for the first time (my car parked in the airport did not start). during the travel I was shocked to notice that it goes through all ugliest parts of Rome, the sight is really depressing. Even when it gets near the town center, the sight is far from nice and someone who sees it after a long flight is likely to get rather depressed and regret the decision to visit Rome. Probably it is not possible to find another single path that goes through all the .. less nice parts of Rome as the Leonardo Express does. So, if you find yourself on that train looking at that depressing sigh don't get discouraged, the rest of Rome is much much better, the Termini Station is not exceedingly beautiful but is OK, the rest of the town center or Rome is very beautiful, it is messy untidy noisy but beautiful
OK, that's all for now, it's not much but I hope it spares someone traveling on that train a depressive crisis :-)
