Pros: The rooms have amazing air conditioning which is crucial in Rome in July and the location of the place is amazing with a close walk to coliseum, etc. Also, Ornella gave us a ton of good info when we arrived and a map of Rome. The rooms are cleaned daily, too which is nice.
Cons: When we arrived we were put in a nice large room (though the bathroom as kind of dirty/gross) which faced the street but we were told we had to move the next day to another room which turned out to be much smaller and faced the inside of the building. However, she did give us a bottle of wine for the inconvenience which definitely helped. Another bad thing is the towels are not replaced everyday (it was either every other day or every 3 days). Also, the towels all smell gross (like vinegar).
Overall: The host and the rooms were satisfactory and a great value. I would stay here again! Also, given the air conditioning was amazing, I would highly recommend Dandi Domus to any Rome air bnb traveler.
