Dear Sirs,
we are planning to stay at Buonconvento near Siena.
We will leave Buonconvento on Monday morning (October 8), and we will have to take a domestic flight from Roma-Fiumicino airport at 1730.
We checked the trainItalia site, however there are so many changes.
Are there any direct service from Siena/or somecity near by Buonconvento to Fiumicino Airport?
If we have time, we want to explore Siena city on the way to Fiumicino Airport, however we have large baggages.

We want to know following points:
1. From Buonconvento to Siena
There is only one train in the morning whch leaves at 8:18. The owner of the accomodation says that its too early to eat breakfast.
Are there any bus services around 9 o'clock to Siena?
2. Are there any baggage storage in Siena?
3. Are there any direct service from Siena to Fiumicino Airport?

Thank you in advance for your help,
Masa
