Just slightly off-topic...
The Westin Rome is a really nice property. I received a great upgrade there not long ago. Booked my corp discount rate but was upgraded to a beautiful 2room suite overlooking the Veneto. ^ They have earned my future business with the great treatment. :-:
Staff seemed very friendly and effecient to me.
Used the Leonardo Express to get to Termini (cost was about $15 US each one-way). And then grabbed a cab to the hotel (not far, but uphill
), which was another $10 USD as I recall.
Hope you have a great trip! Rome is awesome!!
