Lisa's place was just perfect in every aspects - nice, safe and quiet residential area in beautiful Trastevere (Trastevere itself is a must-see neighborhood in Rome), conveniently located to the main sightseeing especially to Vatican city - I walked everywhere but a bus stop is around the corner too, clean/well-equipped/beautifully decorated place, easy&fast communication with Lisa and Alberto, close to nice restaurants and bars. I travel Europe quite a bit and this place was one of the best places I ever stayed. Thanks Lisa and Alberto for the great hospitality and good recommendations.
