The place is great, so nice, it's within 5 minutes reach of metro, tram and bus. It's pretty comfy. We arrived earlier than said and were able to enter the apartement without too much waiting.
The balcony is great for morning coffees with view.
Little, tiny thing we didn't like, it was a hot week in Rome, over 32°C and it was hot to sleep, the AC is in the kitchen/dining room and it doesn't reach the sleeping room, so we opened windows and balcony door to get some air.
The neighborhood Pignetto is nice, you have few bars and restaurants 3 minutes walk from the apartement.
All in all, I recommend it:)
