Staying at Valentina's place was a great experience. She picked us up from the metro station with her car and took us to the apartment and on our way she even made some circles around to show us the area. Then she spent 30 mins showing us the apartment as well. It is nicely renovated and has everything you need to feel like home. It totally matches the pictures. The neighborhood offers multiple places where you can have something nice to eat, couple of supermarkets within walking distance and the best of them all - the Torrefazione Adriatica - a place, where nice people offer great real Italian coffee and nice croissants for breakfast. The metro stop Conca D'oro is just 5 minutes away, but you don't need to bother, because much closer is the bus 90, which is an express line and takes you straight to Termini for no more than 15-20 mins. If you ride it, you can enjoy great Italian houses and buildings. The area is so green, it's like you are not in a city, but in a little Italian paradise.
Don't bother looking for a place in the center - you'll be right in the middle of the tourist craziness, with lots of people offering you "selfy sticks" and other stuff. You better go with Valentina's place to enjoy the Italian life. The attractions are just one bus-ride away. :)
If we are coming back to Rome, Val's place will be our choice again for sure.

Thank you, Valentina!
