Chiara's apartment was very clean, cozy, and spacious. The showers are quite large for Italy and the kitchen was modern. The location is amazing -- it's not more than 20 minutes' walk to any of Rome's main attractions. The shopping areas nearby were beautifully lit for the winter holidays.
My only minor complaint is that the Internet speed in the apartment was a bit slow (only about 7mbits down), but our mobile service worked well from inside the flat and therefore it wasn't really a huge issue. It was good enough for some basic Netflix streaming, anyway.
We would happily stay with Chiara again.
