We had a wonderful time at Marta's appartment. For us, the best thing was it was quiet. We stayed over New Year's Eve, and it was quiet!!! Marta herself was very accommodating when we arrived, explaining which restaurants to go to, which sites to see, etc. She also organised a taxi for us from and to the airport. The internet works very well, which can't be said for most of the other appartments in Rome, so that was a big advantage for our needs. All in all, a very pleasureable experience indeed.
