We loved the apartment!
The location was great:
we could easily walk to Villa Borghese and Galleria Borghese. There is a supermarket on the street of the apartment, in the direction of the park, so it was perfect for picking up groceries on our way to a yummy picnic there.
It's important for us to have a room where you can close the shutters at night, so the sun won't disturb us in the morning: these windows had EXCELLENT shutters so we could block the light out entirely, which was great.
Having a washing machine in the apartment was super comfortable.
The water in the shower were hot and available at once, another thing which is important to us.
Everything was VERY clean, when we needed more towels we asked for them and got them quickly.
The location is great also because there are several bus lines that stop in the street near the apartment, so it was very easy to get into town and back.
Enjoy your stay! - we did :)
(just take into account that the check out time is *very* early: 10:00. We didn't pay enough attention to that detail.
