There are two apartments connected, so feels like a small house with two kitchens, 3 full bathrooms, and 3 bedrooms total.
Pros:
The beds and couches were very comfy (not too firm or too soft)
There were shutters and blinds to block out light
Lots of space for a big family
Great location (5-10 minute walk to St. Peter's square and less than 5 minutes from the metro)
Very helpful host when we had questions
Well decorated
Didn't hear noisy neighbors
Cons:
The street can be a little noisy at night, but that's expected in the city, and I was so tired at the end of the day, that I slept great. There was also construction going on on the roof starting around 8 am, but not much of a problem.
