We loved staying at Alessandra's place. It is right near Piazza Navona and a good place from which to see the sights of Rome. Our family has two kids and it was nice to have our own rooms both on the same level and separate from the living area. Nice not everyone had to have same bedtime.
Apartment is as pictured and has small, but useful kitchen with a few basics. Make sure you use the sugar for coffee--not salt!! There is a large fridge, dishwasher and washer. Keep in mind dryers are uncommon in most of Europe, but there is a drying rack and plenty of space for it.
A/C works well and it cools off very quickly.
The street has a private entrance and it was difficult to find at first. We of course got used to it. Taxi stand around corner is very useful and always had cabs. Some drivers knew just where to return us, others a little confused.
Because we had our kids and were coordinating with friends we did rely on taxi more than public transit. Buses are nearby but Metro does not have stations in the area.
Lovely, lively area with lots of restaurants.
