The hotel could be very beautiful, especially at this location, but many things are Italian-style badly organized/structured... There are like five elevators spread out over the entire hotel, and you cannot just take any of those to get everywhere, no, you have to know exactly which one to take to eg. reach the swimming pool or the roof-top bar, because some do not reach up the 6th floor, and even on the other floors you cannot walk through to the other side, you have to go down to ground floor to reach the right side where the elevator to reach the roof is. And to make things worse, this elevator did not stop on our floor (3rd), for some stupid reason there was no button for floor 3. Amazing.
When we arrived, the guy at the reception just told us to go to elevator 2 to reach our room, but given there was a party on the ground floor, the direct way to that elevator was not permitted, so we walked around like fools for 10mins to just find our room...
At the breakfast, they told us that they will bring coffee which never happened, so we just served it ourselves. In the room there are like 15 light switches, not a single one had a tag saying for which light it was, so it was like a constant exercise to find the right switch for the right light...
For Hilton, I'd definitely expect a better organization and management!
