I spent two weeks in Armando's apartment, and I thank him for being so attentive and quick to respond. The apartment is functional, clean and well located, as I like the area of Prati, and what is very important is that the windows in the courtyard of the building keep the peace and quiet during the night and day. All in all, everything went well, except for the air-conditioning repair which didn't work very well.
However, I would like to point out that the cost of using the air conditioning is not included in the price of this apartment. Although it is noted on the page of the apartment, this rule is so unusual that it is not normally intended when making a reservation. So I was surprised by this restriction to request the use of air conditioning, because in Rome during the summer it is impossible to live without it.
