The location is good as it's near the Metro line (Pentana sta.) and several bus lines 81 (the one we used). I suggest getting a 2 or 3-day metro pass if you want to leverage Rome's public transport with the Google Map as the guide to plan out your travel route within the city even though all the landmarks are all within 20-30 mins of walk.
Both bedrooms and baths (each within the bedroom suite) are clean & sizeable - all recently remodeled. There is even a sauna room. Good decoration & nice furniture as shown in the pics. The entire place is definitely double or triple the size of your typical hotel 1-room space.
Nicola was superb in accommodating us for a 12pm check-in as we arrived from Florence and also arranged a 4:30am pickup (mini van for 4 of us) from the apt to the airport (55 Euros) on the day of our departure.
One thing to note is that the apt is on the 1st floor and close to the pedestrian sidewalk and so you'll hear the passing pedestrians talking till 11-12 at night (but not much of bother). Daily garbage truck pickup noises. All is the typical unavoidable city noise on every Rome residential street block (just like New York city). Other than that, the apt and location are superb.
