I was going to suggest one of the uber options but read that they're more expensive than taxis in Italy. Bolt was the best, most efficient, cheapest way I travelled in Eastern European cities. I love the Trainline app too! It's been a long time since I've been to Tome- there were 6 of us and we booked a van ahead of time. From memory it was 80 euro, not too bad when shared between 6.
