We were in the sister Hotel "Ambassadori", probably due to COVID so there's less work (also because there are less travellers).
The hotel is classy boutique style. We enjoyed time in the bar in a sofa by a virtual fire.
The bedroom is clean and the bed really comfy. The room was made up every day even when we left the room late.
The room is soundproof to the potential noise outside, but not at all between rooms... So you hear the neighbors chatting, the maid hoovering and knocking into the walls, and when the toilet flushes you think you'll be getting a bucket of water thrown on you ! But overall, it's not a problem (plus I always travel with earplugs).
The location is excellent to visit all of the sites on foot (we took a taxi up to Piazzale Michael Angelo, and walked back down).
We can recommend the Florentine steak restaurant just nextdoor, the restaurant and cocktail bar"Oggi", the "Dragonfly" steampunk deco bar, the "Rex" for cocktails and electrojazz.
