This is a wonderful apartment in a non-touristy part of Rome. The neighborhood is truly authentic--you get a feeling of the real Rome. Walking around, you see only locals. The nearby marketplace, Mercato, is delightful, with fruit stands, coffee shops and other local wares.
The apartment itself is a walk-up, 4 flights of stairs. Wasn't a big deal for us. Also it is relatively far from the main touristy areas, again, not a problem for us. But took about 25 minutes to walk to central parts.
Even though it is a fairly compact place, having a nice living room and dining area adds some nice spaciousness. There is also a nice walk-in closet which allows you to store your clothes clutter out of the way. There is an A/C in the bedroom, the living room, and the dining area, and even in the hallway, and they all worked perfectly.
The hosts were very responsive. We had some hot water issues, and they responded promptly, even on a Sunday.
There is a nice view of the Tiber river, through the trees, which gives a sense of openness in the apartment.
If you are looking for a nice respite after a day full of sightseeing, and seeking to feel that you are part of the real Rome, at one with the locals, this is the place.
