I would absolutely recommend Valeria's place. The apartment was clean and pristine. It was really nice to have a washer available for a week long trip! Valeria was such a great host. She gave us really precise directions and great recommendations. Having the bus stop right outside of the apartments was so handy. We took the bus or trains the whole time, so we definitely saved a lot of money on transportation. There are neighborhood shops nearby if you wanted to grocery shop, because the kitchen is perfect for cooking if you don't want to eat out. Although, I can't imagine why you would come to Rome and not eat, the food is to die for! The neighborhood felt very safe for 2 females staying alone. It was so nice to stay in a real apartment home vs. a hotel. There was dish soap, hand soap, laundry detergent, tons of pillows, plenty of towels. In the kitchen there was a kettle with tea, and a Nespresso maker with pods. The tap water was great, so we didn't have to worry about bottles of water.
It would take about 45 minutes (depending on the time of day) for us to get into the city center. It was super easy to get there via the bus (use the App "Moovit" to help you get around). So just be aware that you are a bit further out in a Roman suburb, but honestly this made it feel a bit more peaceful once we got home because the neighborhood was super quiet. The 98 bus takes you all the way into town, and the 786 bus takes you to the closest train station, Trastevere.
I could go on and on about how great our stay was. We had a blast, and having Valeria's place to call home for the week made our trip great!
