Catharine was a great host! She was very welcoming when we first arrived and offered us a bottle of wine. When we had some issues with the wifi, Catharine gave us the keys to another of her apartments to use the wifi until ours was fixed. The apartment was very comfortable and has a great view off the balcony. The apartment is about about a 10-15 minute walk to the Vatican, and although it is not near a metro stop, there is a bus nearby that takes you right into town. It is very close to the Roma S. Pietro train station, which made it very handy when we had to go to the airport.
