Valeria's apartment is in a great location above the metro station. It is very clean, spacious, and well-equipped, with convenient elevator access, a well-stocked kitchen, and a lovely balcony.
Valeria was very nice and quick to reply to my messages, although I didn't get to meet her in person. Her assistant Angela checked me in and was also nice.
The location is great for access to public transportation. Keep in mind that the Rome metro is not dependable (there were no trains going toward Rome during two days of my stay, so I always needed a backup plan). Fortunately, the apartment is also very close to a tram stop, which I used whenever the metro was down, and it was a great substitute. When the metro is running, the apartment's location is perfect because the front door of the building is just 30 seconds from the metro station entrance.
I really liked the balcony, which has a great atmosphere. Since the apartment is on the sixth floor, I loved how you have a great view of the soccer field across the street where there are often entertaining matches.
During the 7 days I stayed at the apartment, it was about 38°C (100°F) every single day, so I really felt the lack of air conditioning. There are large fans in the bedroom and kitchen, but they are not very effective at that temperature.
There is a large smart TV in the bedroom with Netflix, some local channels, etc. It is a great bonus amenity.
The WiFi was quite slow, so my Zoom meetings kept freezing or dropping out, which was frustrating. I kept moving between different rooms to search for a steady signal but was unsuccessful. For other work, like checking email, the internet was fine.
To summarize, I would definitely recommend Valeria's apartment to solo travelers or couples on vacation who are looking for a good location from which to explore Rome via public transport, especially when the weather is a little cooler.
