Monica and her sister Ambra were great hosts, and the apartment is in a fantastic location, very central to main sights. The rooftop terrace was a great to have as well -- excellent for enjoying wine in the evening.
The apartment itself was a little smaller than expected for our family of five (though everyone fit!), and as some other reviewers have mentioned it can get noisy at night, but overall this is a great base for exploring/vacationing in Rome!
