Apartment was cute and in a great location, but several things were broken. We stayed there for a full month but the fridge didn't work the whole time, we only got a new fridge for the last few days of our stay. The dishwasher handle, trash step bar, and bathroom cabinet door was also broken. Would be a much nicer place if those things were fixed. The apartment is also a bit dark, so it's ok if you plan on going outside a lot and won't be staying in during the day, or don't mind it being less on the bright side.
Overall Pierre was a great host and very responsive. The neighborhood is nice, you're right next to the Pantheon and there's a lot of little streets with shops and restaurants within walking distance.
