This place is fantastically positioned to see Rome. It's within walking distance of both a subway stop and the main train hub Roma Termini and has both a supermarket and tons of restaurants nearby. It's also pretty nearby the Colosseum too so that's a major plus.
The apartment itself looks fantastic and was fun to stay in, though it had one or two minor issues. The toilet was finicky and there was some dust in places, and if you come in the summer months, be warned: you will get very hot. There are fans to help with this but this place holds heat very well despite this.
That being said, this is definitely a recommended stay. The location is unmatched and the decor was beautiful. Also, having great water quality was a huge plus - as small as that may sound. Ehsan is very quick in his communication and will make suggestions on local things to do and how to get around effectively.
If you're looking to explore Roma, keep this one in mind!
