Nino is a wonderful host, and yes, he does live right next door (the apartments share a main front door). He was very helpful for first-timers in Rome- showing us around the neighborhood, where the grocery store, bus, tram stops, etc, were. The apartment is very clean, spacious, and the neighborhood always felt safe, even walking around in the evening. It was a great value and a good location, even for first-timers! (Note for those with physical limitations: There is a very small weight limited elevator, but first you must walk up a small set of stairs to get to it.)
