I am talking about the De La Ville Intercontinental.
The main desk gave me a real lousy room, the worst one I ever got in a good hotel. I got a nice room through the lady on the "VIP, Executive" desk (I am no more Ambassador, but Platinum).
When you enter the hotel, don't go to the main desk (which is right in front of you), go right into a small hall and you find this desk on the right.
As mentioned before, it's a little tricky to get to the hotel. It's a one-way-street: first comes the IC then (next to it) Hassler (everybody will know Hassler in Rome) and then you are on top of the Spanish Steps. Check Hertz at Google Maps! Still, it's a good idea to take a car from Sorrento to Rome, you can make it^ You can always stop and check the map, Never Lost would even be even better, but it's OK without it. BTW, In Rome itself, a car is useless.
