We had a great time at Daniela's apartment. She arranged airport transfers for us and check-in and checkout was very easy. The apartment is so lovely, we loved sitting on the terrace.
The location is good. We found the tram was more reliable for getting in to Rome but the bus was easy to get to the Vatican. Trastevere is nearby (short bus or taxi) and great for dinner as it has loads of good restaurants. There is also a couple of supermarkets within walking distance of the apartment.
Would definitely recommend Daniela's apartment for a trip to Rome.
