This apartment has a great location! Literally a few steps away from the metro station entry. There are also lots of local restaurants and grocery stores within 100 m or less. Also a park with playground equipment. A great place to explore Rome from.
Overall the apartment is a great 2 bedroom 1 bathroom. Note that if you use the 3rd room as a bedroom (which has a couch and separate door), there is not much living space. The dining room and kitchen area is very, very compact, and would be hard to use with more than 4-5 people. Also, keep in mind that the apartment is a basement apartment, but even so, has a lot of great natural light (sunken courtyard on the opposite side of the street helps it not to feel like a basement).
The apartment was showing a little bit of wear, but otherwise was as pictured. There were a number of great amenities, and seemed the hosts had thought of lots of things, from local guide books, to umbrellas, to toiletry items.
Finally, location is incredible. Perfect place to be out of the main sightseeing, touristy areas, while still having very easy access to them.
