Location was great, only steps away from the Pantheon and ~5 minutes from the Trevi Fountain. It was close to a bus stop that took us right to the Colosseum as well.
Carola arranged for us to be picked up from the airport and the driver was very helpful--he brought our bags right up to the apartment
The apartment itself was modern. It was a bit small for 4 adults and you had to walk through the main bedroom to get to the bathroom. There was an elevator that brought you right up to the apartment which was convenient. The bedroom had a safe where we could store our passports
