This apartment is in an incredible location. Trastevere is full of restaurants, bars, trattorias, and gelaterias. No need to eat in Centro Storica where you might be getting bad tourist food. if you want great pizza, pasta, authentic Roman cuisine, pastries or gelato you can find it for a decent price in Trastevere. There is even a great microbrew pub that has great pizza, Bir & Fud.
You are also in walking distance of all the major attractions - Spanish Steps, Trevi Fountain, Colosseum, Palatine Hill, the Vatican City, and the Pantheon. You should never take public transport in Rome, enjoy walking the streets and discovering the sights. And buy your tickets ahead of time, things sell out.
There are a few things to be aware of. It was hot in July in Rome and the AC was only able to keep the bedroom cool. But the tapwater is cold so taking an afternoon quick cold shower to cool off worked well. The only other thing is watch out for the sloping roof over the bed. You are warned not to hit your head and they are quite serious about it.
All in all, a good apartment in a great neighborhood. Would stay again for sure.
