It may not have been a discount. I just checked the website and the price from FCO to Rome hotel is 60 Euros and the price from Rome hotel to Port is 140 Euros. This is what we are paying so I guess it's not actually a discount.
I just booked Rome Cabs for our October TA. They have some discounts going on now and it was much cheaper than getting transfers from anywhere else. They got right back to me with a confirmation. Looking forward to doing business with Rome Cabs.
Good review @FionaMG. We will be staying down the street from Hotel Lancelot at the Hotel Capo d'Africa. Does anyone have any reviews on this hotel? I have not seen any on this thread.
