Which bus do we take to the top of the Janiculum? We want to walk down and continue a long stroll that day. Our hotel is near Termini. Is there a way to find out what bus to take? Or would a taxi be a better bet?
you need the 115 or the 870 from the Vittorio Emanuele II bridge area.
The no. 40 goes there from via Nazionale.
have you tried to search itineraries online?

The #40 also has somewhat of a reputation for pickpockets (although not as bad as the #64), so you'll need to be vigilant. DON'T forget to validate your ticket!
Thank you both, we will go online as well...
