Cristina was a wonderful host. She met us outside the apartment even though our train was a little late in arriving. The apartment was very quiet -- and on a quiet street -- and in the heart of the historic city center near Santa Croce. There are several trattorias nearby and it's an easy walk to all the city sights. The apartment is a "penthouse" on the 2nd floor walk-up.
Cristina had left us a bottle of wine and a few snacks for our arrival. The apartment was well laid-out and clean. The water in the shower had a tendency to fluctuate in temperature, but in such an old building, it's understandable. Cristina was very easy to reach and she was kind enough to order us taxis a couple of times.
I would absolutely recommend a stay at with Cristina!
