Marco and Nora were excellent hosts. They took me in at short notice (4hrs) and provided me with plenty of helpful information. Their collection of fliers and brochures is almost as big as the one you find in the tourist office.
The communication was great though both only speak intermediate English. Nora is fluent in Spanish though. The rooms Marco and Nora provide are spectacular. They are decorated with style (apparently the style of the 50's) and they are probably the cleanest rooms I have ever seen.
Both truly appreciate their apartment and that is the way how they keep it. Every room has a TV and WiFi internet access. The apartment is just a few meters from one of Rome's biggest city parks (if not the biggest) - Villa Ada.
There are small boutiques, shops and restaurants around the corner as well as the King cinema. The connection to the city center is great. Multiple buses run till 12.30am in the night. It is about 20-30min to the city center. To Vatican City it is about 40 min. To help you get going for the day, they usually served traditionally excellent tasting Italian espresso, muffins, croissant, toast with jam, eggs and a joghurt for breakfast.

We would recommend a stay at Anni's 50 Bed&Breakfast in a heart beat. I would stay there any time again and wish both of them all the best.
