The apartment was very central and only a street away from the train station. If you're driving a rental, the car park where you pick up the rentals (from Rome's Termini station) is only a block away (you can also park there for the night).
From the apartment, you could walk to a couple of attractions (colosseum would be one of them), for the others, there is the Rome Termini station where all trains/trams/buses originates from.
There is a cafe across the street if you fancy a morning coffee and an Indian Fast Food joint which is also nearby (ask Antonello)
The apartment was well appointed with all the amenities listed. Loved the loft bedroom!
In all our stay was awesome! Thanks to Antonello who accommodated our late Check-in (due to a faulty GPS and a long line at the Colosseum) and who pointed out all the nearby food joints and directions for public transport.
