Vincenzo is communicable and friendly host. The apartment is very spacious and is very comfortable for 4 guests (two couples). Location is really one of the best possible options in Rome, every time i come to the eternal city i stay in this neighbourhood. It has great supermarkets, gelaterias (Millenium is my favourite) and restaurants. And at the same time it`s just a couple minutes away from Vatican city and Sant`Angelo castle.
If you are going to visit Rome in a group of 4 people - this apartment is a good choice
