Sergio's place is a great place to base your Rome trip. I had heard that Rome can be an exhausting place to get around, but Sergio makes the city very accessible. It is located about ten minutes on foot from Termini station. The apartment is less than five minutes from the metro (which is not incredibly useful in Rome, but gets you to some places), and is surrounded by many bus stops. Sergio was very helpful in providing us the best routes to the places we wanted to see, giving us a map and the bus numbers. Although the neighborhood may seem a little seedy, we always felt safe. Sergio is accessible as you want him to be. He is always willing to answer questions, but if all you want is privacy, he disappears. In all, we had an amazing couple days is Rome, and Sergio was a big part of that.
