Very good location (metro, train station and bus stops) to sightseeing the centre of Rome, but really not necessary. We prefered walks along beautifull Rome's streets. The flat very nice, clean, silence, full equipt, even if you want to cook yourself. We were the first guest. The owners very helpful in giving usefull information how to get somewhere. For invitation they prepared for us some snacks with a cold champagne in a fridge :) So it was very nice, especially if you arrive late evening. Also we could choose the hour when we want to leave the flat.
We have spent fantastic time during our 4 days trip in Rome.
Wish you all the same :)
