This was a very nice apartment in a vibrant area. It was very clean and had all of the necessary linens, kitchen equipment, etc. Do not be fooled by the graffiti during the day- the neighborhood really comes alive at night with all kinds of restaurants and bars. We wish we had spent more time in it. I don't know that I would recommend it for families with kids, as things tend to open pretty late, and you do still have to walk a little to get to most of them.
One thing to be aware of is that the apartment is NOT "next to" Termini Station, unless you consider a 20 minute walk along very busy streets to be close. The closest station, Manzoni, is a brisk 15 minute walk. The closest grocery store is next to Manzoni, a 12 minute walk.
Given the price of staying in the more touristy neighborhoods of Rome, I think it was definitely worth it, and the host was very accommodating. We had to come in a day later than planned, and he was very helpful making it work for us.
