Mom, Dad, Linda and Leon left yesterday. It was great to have them here. I was able to use all the knowledge I've learned about the city to be their tour guide. They stayed at a hotel about 5 minutes from me so we met in the mornings for breakfast and decided what we wanted to do.
One of my favorite places we saw (one of the only places I took them that I hadn't seen already) was the Church of Sant' Ivo. A small church by Borromini with a concave facade and triangular based floor plan. At a glance it looks like another "Italian Baroque Church" but Borromini's work I'm discovering was pretty revolutionary.
We also went to the small seaside town of Sperlonga for a day. It is only about an 1:15 minute train ride from Rome and another 15 minute bus ride. There are the remains of a seaside villa and pools where the Romans had their own fish cultivation.
