We had a great stay at Simona's place. We loved this location and the pad is super nice, clean, and well situated. Restaurant Da Massi down the block offered one of the best meals we had in Rome. We also appreciated using the nice kitchen and provided amenities, including wifi, dishwasher, and clothes washer, and enjoyed the pleasant balcony. It's also impressively quiet at night, as other reviewers have mentioned (though we could sometimes faintly hear a night-owl neighbor's TV in the middle of the night). Rather minor complaints would be that we weren't left with much toilet paper and had to buy more within a couple of days. Also the fold-out sofa bed is not super comfortable, but our kids got used to it.
Overall, I would definitely recommend Simona's pad and would love to stay here again!!
