Hey there,
Rachelles place is very comfy and clean and you have a big library of books and some musical instruments in the room. A soft matress and an own bathroom which is quite important in rome during the summer. The parks in the area are super nice. You have to calculate around an hour into the city center by bus.
Rachelle answered all my questions timely and was flexible with my arrival time since my plane landed two hours late. She can also recommend a good pizza place in the area 😉.
