Nani treated us with a warm welcome. Gave us all necessary instructions concerning the apartment and Rome. There was water in the fridge and cookies on the table. The apartment is very clean, and with 3 windows - with a view on the street and a on little square - it's light. Trastevere is the perfect neighborhood to visit Rome, outside the crowded and busy city, it's a kind of city of its own. With everything you need around you. It's a quite place, not noisy, so you can sleep well (and if you don't want to sleep you can go to the nice pub around the corner). If you want you can cook and eat in the kitchen. The sanitair and shower are very good.
So ... perfect place. We would definitely go back next time.
