Andrea was a great host. We arrived quite late in the night around 11pm and Andrea and his wife were waiting for us on arrival. The gave us a tour of the apartment which is absolutely beautiful and even walked us to a local pizza restaurant that was open near the square. The apartment is very clean and comfortable. There are all the necessary amenities and the wifi is really fast.
Andrea and his wife also have a visitors book with all the nearest attractions and food restaurants to visit in each area.
The apartment is perfectly located if you want to stay somewhere convenient but not too touristy. The metro is right next to the apartment and it's only two stops away from the Vatican.
