Our experience at Paolo's apartment was very pleasant, excellent location for walking to most of the turist attractions; there's also a bus stop below the apartment to go other places including the colusseum and train station.
The view is spectacular: to the left, the Vatican entrance thru the Spirito Santo portal, in front, the impressive San Angelo Castell, to the right, small shops and restaurants, and crossing you view from left to right, the wavering Tiber river. The apartment is very clean with extra large bedrooms. We occupied one of the 4 rooms and shared the bathroom and kitchen. Since most of the guests come for the weekend, we had the apartment for ourselves during the weekdays. The bathroom as you see it in the pictures is very large; it includes a jacuzzi type bathtub, a bidet and a toilet.
The kitchen is small but it's equipped with the necessary utensils to cook a small dinner; the refrigerator is divided in section assigned to each room, where we kept water, milk, fruit, bread and snacks.
Also, there is a small washer and dryer in the kitchen, but the cleaning person keeps them busy most of the time, the washer doesn't function properly and there where no instructions for its use.
Paolo ofter to pick us up at the airport for a €50 fee. This worked perfect for us, since we weren't familiar with the public transportation in Rome. He also gave us the code to the apartment doors. The apartment doesn't have air conditioning which may be a major problem in hot weather; other problem is the noise if you keep the windows open. This is a trade off for the excellent location. I recommend to bring some ear plugs if you want to keep the window open to cool off the room.
