A wonderful central location, being right next to the train station (30sec walk) was of great value to us. Perfect size for a couple or three close friends. Slightly smaller than we were expecting but that was largely a fault of our own expectations not any fault of Giuseppe. Giuseppe was a truly wonderful host and we would happily stay with Giuseppe again! Quick walk to the Vatican City, as well as a grocery store (With all you could possibly need to cook whatever you wish), and several wonderful restaurants.
Only one small issue that we had: The shower (or any hot water in this apartment) is operated by a small hot water tank. So long as you are okay with taking a quick shower this is not a problem at all! If you're planning on taking a long shower this setup will not work for you.
Thanks Giuseppe!
