Everything was fine. The place was easy to find, the location was convenient since it was a 7-minute walk away from the Roma Termini station. Also, it was easy to travel from and to the airport: one could take a comfortable express train or a cheaper bus at Termini.
Walter has done a good job anticipating every possible need we might have. we had at our disposal a coffee maker with enough pods, oiive oil, a full set of utensils, etc. The apartment was also very clean and meticulously maintained, the kitchen, bedroom, and living room were spacious. There were two small bathrooms, one of which had a washing machine.
The temperature in the apartment was set at 21.4 degrees Centigrade due to restrictions related to the war in Ukraine. One of the bathrooms was equipped with a small wall heater which was able to heat it within seconds.
All in all, we had a good experience and would stay at that apartment again.
