This was a large clean apartment on a quiet (for central Rome location) street. They will meet you (thanks Rudi!) and answer all of your questions.
All appliances (including A/C and the washing machine) worked perfectly and the towel/necessities supply was comprehensive.
They will also arrange, if requsted, a UberBlack-level transportation (Mercedes van or sedan) from/to airport for UberBlack prices, with the bonus of the driver waiting for you at the arrival area and walking you to their car, instead of you having to search for the pickup area.
