We didn't get to meet Federica but her friend who checked us in was great and very helpful throughout our entire stay. Both he and Federica were always readily available when we needed anything and the communication was great throughout the entire reservation. The apt is very spacious, easy to get to from the SMN train station, and extremely quiet. The terrace and location are beyond AMAZING! There's a woman who sits on the first floor of the building who was also really helpful with little things as needed. Can't recommend this place highly enough and would book it again in a heartbeat.
