The apartment was very nice, just as described. Perfect for two people. Kitchen has everything necessary if you're willing to cook during your stay, as well as biscuites and coffee :)
The apartment is conveniently located in a very quite neighbourhood, there's a bus stop just around the corner from where you can easily get to Termini. The metro (Re di Roma) is approx 10 minutes walk. Btw, a walk from Colloseum to the apartment took about half hour.
Concetta and her husband were very welcoming and of a great help before the trip and during our stay.
The only thing you should get used to is pretty thick walls between the apartments.
Highly recommend for your stay in Rome!
