The Upside: The location of this place is absolutely perfect for exploring the most charming heart of old Rome. It is literally only one block west of Piazza Navona. The Pantheon, the Vatican, Palazzo Venezia, and the Colosseum are all within easy walking distance. The apartment is in itself nothing special, but is clean and functional as a home base. The a/c works really well, and if you close the shutters and door to the kitchen when you leave for the day, it's still pretty cool when you get back.

The Downside: Though it might simplify the process, there is no need to take the private transport he offers after booking. His directions are a bit murky when they do not need to be, and he may get something of a kickback as the charge is 60+ Euros (depending on time and day), while any city taxi charges 48 from FCO airport to the city center (non-stop train + bus + the walk = 32 Euros for two people, so the taxi isn't a bad deal). Have the taxi take you to Piazza Navona and you are less than two minutes away.

The fridge needs to be plugged in to work, which isn't a big deal, but it did take a bit of finagling to get it to work. As he has to come to meet you, it would be nice if he did this before arrival. The only real issue is that the place lists "washer" as an amenity and does not have one. The nice older lady living upstairs will do your laundry for you it seems; however, my wife has several fabrics with special care instructions and thus, it was effectively like not having a washer at all.

Summary: These issues aside, I would absolutely stay again. I cannot emphasize how amazing the location is. It could have been a run down dump (which it was not) in this location, and we would still take it. Once we were there, the host was easy to communicate with and helped us with the couple of things we asked for and answered our questions promptly.
