This place is very close to the Roma Termini. Antonello recommended a food hall type establishment in the station which was great. (You wouldn't think of the train station being great for food, but it is - full of locals too).
The bed was very comfortable with high quality and soft bedding. The shower was large and had good pressure, and was satisfying after all the walking that comes with Rome. And the apartment was extremely clean.
The place is compact, being an apartment in an old building that has been converted into two studios. The conversion has been done tastefully, maximising the space with a bed deck and a little spiral stair case. This is high density accommodation in an inner city location, so it served me more as a conveniently located stop-over than a place to hang out in and unwind.
Thanks to Antonello for being responsive and flexible with meeting/check-out times, and sorting me out with somewhere to stay at very late notice.
