The main thing is that he apartment is huge: 2 fully fledged living rooms (one with a pool), 1 very large dining room, 1 kitchen, 2 large bedrooms (and a smaller one that we didn't even use).
On top of this, the apartment is very well located next to Piazza Barberini where you can find handy electric scooters to reach Trevi's fountain or the Spanish steps in like 3 minutes (or 10/12 minutes walk).
It's also clean and has everything you need nearby.
I definitively recommend it!
