Dario is a great host. Very responsive and attentive.
The apartment has a nice residential style to it, comfortable and with a lot of light. The master bedroom is huge, the other two bedrooms a well sized, the living/dining room is smaller but accommodates 4 no problem. Kitchen also has a table that seats 6.
The location is great. The area is quite residential, you feel like you are living in the real Rome, it is not packed with tourists. Yet it is only a 30 minute walk to practically all of the interesting locations in Rome. Well connected by bus and a short walk from Rome Termini.
I would definitely recommend.
