My wife and I stayed at Giorgio's place for 3 days in May 2019. The apartment was well-furnished and the room itself (I talk about the bathroom later) had ample space for the two of us. The apartment is on the 4th floor and you have to climb the stairs, but that was not an issue for us. We loved the location. The Pantheon and Piazza Navona were both very close by (5-10 minutes walk). We found Giorgio to be a good host who was quick to respond. There were nice personal touches throughout the apartment, like coke and chocolates in the fridge, and umbrellas in the closet (which were really helpful). The bed was on the firmer side (which I like more than my wife does), and plenty large for two people. There was a water heater in the bathroom and as long as we paid attention to the temperature level we had enough hot water.
The one thing that was less than ideal was the shower stall. We expected the bathroom to be small, but even so the shower stall was quite tiny. Moving your arms around or bending down was not the easiest job. This was more of a minor irritant than a dealbreaker, and we overall had an excellent experience of staying in this place, but you may want to keep this in mind, specially if you are taller than say 5 feet 10 inches.
