Mostly everything. the staff was good though.
Room was clean, nicely decorated, and the bathroom was larger than I would have imagined. I'm a tall person and had no trouble in the shower (assuming you are used to turning water off while soaping up). Breakfast was nice - typical Italian breakfast options - and the coffee/espresso based drinks were very reasonably priced. WiFi worked great in my room.
Lots of stairs to get to reception and the lift is quite small.
