Our stay at "Navona Taste" apartment was our second rental from Maurizio & Fabio in 3 months (the previous was nearby, in the Rome Ghetto). The photos are absolutely accurate about the amenities and layout. But best of all is its ideal location between Campo de' Fiori and Piazza Navona, with numerous restaurants and shops just steps away. Its central location allowed us to walk to all of the major sights (Colosseum, Vatican, Borghese Gallery).
For those not able to handle steps, the apartment is on the 2nd floor and there is an elevator that lands a half-flight above and below the apt. It is quiet for a downtown location, although you will notice late-night noise on the weekend. We did not prepare any meals so we can't speak to the completeness of the kitchenware, but we really enjoyed the espresso machine.
Maurizio & Fabio provide an outstanding renter's guide with instructions on the appliances, recommended restaurants, local walks, etc. All communication was very prompt -- they are old hands at taking care of visitors. We strongly recommend having them arrange a driving service to and from the airport as Uber has been restricted. I do NOT recommend a taxi (after a crazy nighttime drive, the taxi driver tried the old scam of saying that I had given him a 10 Euro bill instead of a 50, which has similar coloring).
