Maria's place is in a excellent location, walking distance to the Vatican and there are a lot of local services including markets, bakeries, eating places, a self service laundry, all the things a traveler will need. The guest room, which included an ensuite bathroom was very clean and Maria and I had no problem in setting me up with my keys and instructions on accessing her building. One thing I would share with fellow traveler is that her place is located walking distance to the San Pietro Train Station (the closest to the Vatican). Don't confuse that train station with the Ottaviano San Pierto subway station. It is still walking distance but it would be a pain if you are trekking with bags in the hot Roman sun. All in all I had a great experience and highly recommend staying at Maria's.
