Amazing central location in Rome - we didn't take any public transport at all and got to all the major sites.
The apartment was spacious, clean and comfortable. We were two adults and two children. Although I would be worried about allowing young children up on the balcony as they could easily fall between the gaps in the railings.
Nicola the apartment manager was responsive to all questions. We also ordered a taxi to the airport through her which arrived right on time.
