This is a 3rd floor walk up apartment with AC that is known to the rental company to be broken. We weren’t told this beforehand and spent our entire stay without AC in a sweltering hot Rome summer. Very uncomfortable experience for several days. There was an “attempt” to fix it on our last day but AC was not fixed. I would not stay here in the summer as the heat in the apartment may be borderline unsafe for some people. The location however is steps from the Vatican which is the only good part.
