First, the location. The listing indicates that it is "just a few meters from the Metro station (san Paolo Stop)". After i booked, the directions indicated that it is 500metres away from the metro stop. In reality, it is 900metres away from the metro stop when i checked Google map. It wasnt a pleasant walk between the metro and apartment with the streets lined with huge rubbish bins though this could be particular to Rome. It was far too tiring for my elderly in-laws to walk back after a day out. Even i also felt that a 15min walk is too far. However the remote location of this apartment made it difficult to get taxis. Taxi drivers refused to take us as it was on the other side of town from the attractions. One even charged us a flat 20 euro from the Colosseo. Antonella arranged a private ride to the airport for us, which was great.
The apartment is bright with a wonderful view of a park opposite. The building and apartment do not look to be recently renovated. There is a musty smell in the lobby with unpatched cracks and holes in the walls. The sofa was old - cracked in many places. The 2nd toilet needed some minor fixing. The toilet roll holder was hanging off the wall with the screws showing. The washbasin drained slowly. The shower area also drained slowly leaving one standing in water while showering. The showerhead attachment was leaking. I was too embarrassed to ask my in-laws if there are issues with their attached bathroom.
The kitchen was fairly functional. We couldnt find any hand cloths or scissors or wine glasses. The terrace was huge and goes around the living room to the bedrooms. The dining table on the terrace was outside the bedrooms rather than the kitchen/living room.

The main issue was the airconditioning (lack of). Knowing it was summer for my trip, i made sure that airconditioning was an amenity. This apartment was hot and stuffy with nonexistent airflow. The first night was so unpleasant that i made enquiries to AirBnb support to see what my options were.
Antonella was able to arrange a service guy to check this the next afternoon. After he cleaned out the central filter, the air flow was decidedly better. We could see that the aircon vents inside the apartment look cleaner. The apartment finally cooled down to 26degrees. Not cold but definitely bearable for the next 2 njghts. We avoided going back to the apartment during the day and sat in cafes instead.
Antonella was responsive and i can see where her superhost status came about. Her apartment was bright and airy with the windows opened. Unfortunately the location is a huge sticking point for us, being far more remote and relatively inconvenient for us. This apartment clearly clearly needs some major cleaning and a total revamp.
