Positives - location is very convenient, just 1/2 block to Metro. Bathrooms were well appointed and spotlessly clean. There were two toilet + shower located next to each other, and a shower / sink in one of the bedrooms. Beds were comfortable. Kitchen was fine. Two of the bedrooms have expansive windows looking out on the courtyard.
Rough edges - the apartment is part of an infill project inside a classic Parisian superblock, with construction ongoing above the apartment. Access is somewhat akward; you pass through the front door of an office complex, down the hall, and then to a walkway through the remaining courtyard to access the elevator.
Paris was very rainy while we were there, and we discovered the big glass ceiling in the main room leaks in several places, and has been doing so for some time. There was also an intermittent leak in one of the bedrooms. The apartment could get very damp from the leaking at times. The walkway through the courtyard had clogged drains, and so we had to walk through a 2-inch-deep 'lake' after significant rains.
