I truly enjoyed staying with Claudia and Antonio in their charming loft. And it is just that, charming and unique. They were both very welcoming as I arrived (exhausted), and even shared their lunch with me at that time! During the entire stay (1 week) Claudia was professional and considerate. During my stay, they were both there each night, but I understand that's not always the case.

Once inside, it is reasonably quiet. There is a small college bar/pub across the street, but the street itself is not very busy with traffic. Inside the flat is very comfortable, the bathroom and shower are hotel quality -- the water pressure isn't super, but it gets the job done. Internet access was fast enough that I could stream video at 720p without much buffering. No problem connecting with either my phone (iPhone) or my PC. The washing machine is tiny by American standards, and drying requires a day or so on the rack, depending on temperaure / humidity.

The photographs of the loft are accurate, but let me give you a little "heads up" -- the flat is on the ground level, there are no steps required to get into the flat itself. However, the loft where the bed is requires climbing a narrow stairway inside the flat, comprising about 9-10 steps up. The loft itself has a very low ceiling. Maybe 5 feet at the top, it was impossible for me to stand straight up anywhere up there. The bed fits back into an alcove, which at the lowest point is only a few feet above the bed. If you have claustrophobia, not the best choice. However, if you love beautiful arched brick ceilings, then you'll find it to be amazing.
Privacy is somewhat limited up there. The rail of the loft is covered, so you have sleeping / laying down / sitting privacy, but standing up would reveal you to anyone sitting / standing downstairs or in the kitchen. Claudia's room is below the ground level, and they close that off to provide some additional privacy for guests (and for themselves).

Just a few notes on getting there: If you're using google street view, don't be dismayed by what you see! It does provide the accurate location, but it's an old picture -- their flat was converted from a retail store that was in that location previously. This is a common trend for that area. Coming from Termini requires a good 15 minute walk. Exit termini on the Via Marsala side, which is on the Track 1 side. Dragging luggage is a bit of a chore, because of the stone streets. You can, however, find "smooth" sidewalk most of the way there if you look carefully. The larger the wheels on your luggage, the better.

Finally, I strongly recommend taking the Leonardo Express from the Fluominco Airport to the Termini. It's fast, easy, and cheap. All-in-all, a perfect location for exploring the beautiful city of Rome!
