Nice hotel and I would happily stay there again. The restaurant and view are great.
Lately, I've come to prefer the Hassler, just a few blocks away.
The location is better, the concierges seem better as does the service. The rooms vary a lot, however.
I just had what must be the best room in the Hassler short of a suite. It's room 403 (how do I remember - I took a digital photo of the door so I would remember - that's how good this room is).
Ask for it - but try to avoid those times when I'll be there!
It's in the corner closest to the Spanish Steps so you actually have a view of them and Via Condotti.
