Cristina is a wonderful host. She will make you feel very welcome and will be the highlight of your visit to Rome. The unit is very close to the metro station and Cristina gives great directions. There is a lovely little Trattoria & Pizzeria down the hill from the main street, via Appia Nuova 598 (but avoid the 'hip' tourist trap on the corner). It is a short metro ride to the Spanish Step and Trevi Fountain. We loved our stay with Cristina & would come again.
