The location is superb: it's right next to the hip district Trastevere, 5min walk to Vatican and ten minutes to the main city centre. View from our room was spectacular. Everything is clean and works but the room was pretty basic and walls seemed somewhat thin at times. Otherwise the cleaning lady is super friendly and you can use the washing machine if need be. I never actually met Paolo or Daniela but they're friend let me in and answered all my questions and helped me find good places to go to.
Highly recommended for easy vacay where location is the most important thing :)
