Anna is really a great host. Start from the beginning, she welcomed us at the apt and wrote down restaurants / supermarkets nearby on a map, which has been extremely helpful. We also followed her advices to take buses to Vatican and really enjoyed the ride. Besides, Anna was also very considerate by helping us arranging luggage storage since we had late night flights on the day of departure.
The apt itself is VERY clean and well-equipped. I really need to highlight it's cleaness as Anna's mom is the one who maintains it. You will have everything you need to make yourself comfortable.
