The connection from Rome to Siena is one of the most simple and comfortable throughout the transport network departing from the capital.
I did back and forth for two years because of the University and I have always found it very well.
Train would required a change at Chiusi and then take a bus to reach the center of Siena - the bus is to be comfortable and always punctual.
