The hotel is very well located and rooms are nicely decorated. But rooms with "street" view are terrible are they are extremely noisy (there is permanent traffic at night in the street and Italians are not particularly discreet as you would expect) ; windows are old and not "sound proof".
We could not sleep for two days! And this for 500 $ a night. Unless you can afford the "river view rooms", do not stay at this hotel!!
