We stayed at Martina's place for a few nights and found it to be perfect in every way. For US visitors, there is AC and it works well. Martina and her mom met us at the apartment, showed us how to find things as well as how everything worked. The apartment is stocked with important basics along with a few extras (like a nail file and clipper) should you have forgotten to pack something. The neighborhood is nicely outside of the touristic zone so you get a feel of being a local. Still it is conveniently located to a metro stop and several bus routes can be accessed. Grocery and restaurants are a stones throw away. Best part is the AMAZING TERRACE! This should be your first pick to stay in Rome.
