Clelia's instructions to reach her Airbnb from the airport specifically say to take (what we found out to be) the most unsafe train in Rome. My wife's wallet was pickpocketed on this train(from my front pocket), and it had $2000 US in it. This was all of the cash we brought for our honeymoon. It soiled our trip because the remainder of the trip had to be put on an emergency back up credit card in my name. The train cost was 18 euro total, but a safe taxi would have been between 20 and 30 euro. All of the locals are aware of how unsafe this specific train is, and suggested avoiding it at all costs. There were no police any where for this train or train station, nor were there any security cameras. We took other trains in Italy (to reach other Airbnb bookings) from Rome to Florence, Florence to Venice, and Venice to Milan. Every single other train station had police everywhere and security cameras as well. It was very clear the pickpockets in Rome target this one train Clelia suggested. When we asked her about it, she denied anyone having an issue and said 14 year old children take this train alone. Something needs to be done to prevent this from happening to other Airbnb customers. A simply warning in advance would have prevented this issue from occurring.
