Alessandra was an amazing and communicative host! My friend and I had a great time staying at her place while exploring Rome.
The space is very cute and functional, but is indeed small. If you are happy sharing space (and a bed) you'll have a wonderful time! We spent a lot of time enjoying wine on the patio.
We walked to most sites from the apartment, but getting to the Vatican and the airport via public transportation was very easy. There are lots of great restaurants around the apartment, but consider getting reservations if you can!
