Great, central location, very convenient for all the sites of Rome. That said, the pictures and the listing might oversell it a tad. The paint was peeling off the walls in both showers. Baseboard trim was falling off the wall. Bedrooms had barely any furniture (bed and wardrobe, nothing else), and the apartment layout was kind of funky (it was two apartments separated by a tiny hallway, combined together).
The Sonder team is very communicative. They're clearly trying their very best, but it's tough when the actual product/experience isn't great. Examples: the code required to open the unit door wasn't working, leading to all sorts of confusion after 20 hours of air travel), wifi didn't work (we connected to another unit's wifi though), there was lots of late-night noise from neighboring guests (3 AM, drunk, wandering the hallways, yelling at their friends). The tiny elevator broke while I was in it and the customer service team's first reaction was that we must have had too many people in the elevator (just me and 2 suitcases). On the other hand, the AC was solid! And the multiple bedrooms gave us plenty of room for grandparents, parents and children.
Would we stay there again? Hmm, maybe not. But did it work out? For sure.
