The apartment was lovely, in a nice old building with lots of character. Views of old streets and buildings from the place, plus a balcony. Very lively neighborhood, surrounded by restaurants and little shops. Very close to everything. We walked to Pantheon and other central cites, as well as to the Forum and the Colosseum. Daniele's mother Ludovica met us on arrival, although we were 3 hours late and showed us the apartment. It was very thoughtfully stocked with milk, juice, coffee, tea and other essentials. Everything worked well and was very pleasant.
Two words of caution: there is no door between bedroom and living room, so 4 people can stay if there are no privacy issues (like us with two kids). Also the neighborhood get VERY noisy on weekend nights. We stayed Fri-Sun and Friday was the worst, with teenagers singing loud songs and drinking outside until 3 or 4 am. However, Saturday was a holiday, so maybe that's the reason. With ear plugs and a jet lag we slept through most of the noise. Saturday was loud, but not as bad as friday, Sunday was lively, but not too loud.
