When you got off the train from the airport, there's no clear instruction to tell you how to go to the hotel as there is no map provided at the station. You have to walk along the platform(from the end to the very front, the platform no.1 as I remembered), then you can easily to find it out at that time. It is just located opposit to the Termini but it is not that easy to find as the Termini is quite big and no instruction really.
The staff at the hotel is nice and helpful; the breakfast buffet was so so; the room is small, esp the washroom. If you opened the window, it would be quite noisy in doing so.
In conclusion, it is not a bad choice to stay at this hotel but I don't think it is a 4 star hotel in a certain extent.
