PROS:
Paolo greeted us on arrival. Check-in instruction was clear and easy to follow. You will have your own bathroom in the unit. Breakfast was provided free of charge and you may grab fruits and milk from the kitchen at any time. Location was perfect, about 7 mins walk from metro and 15mins walk from Vatican City. Cleaning and bed making was an everyday routine.
CONS:
You may *sometimes* hear the next door neighbords speaking through the thin walls. However, I didn't not find it too much of a problem at night.
