The entire place seemed much brighter in the pictures than it actually is, because they were taken with the door open into the street (which you obviously won’t keep open during your stay). Same thing with the blinds - we had to keep them shut because the inside of the apartment could be seen from the street.
The design is lovely (as in the pictures) but be warned it is not as convenient as it seems. There’s basically no place to put your luggage - you gotta keep it either on the floor or on the sofa (unless you travel super light).
As most spaces in Paris everything is tiny - bathroom, loft space where the bed is...
I was mostly frustrated by the inability to let any fresh air in - there are no windows and you have to keep the A/C constantly on, which dries out the skin and is just annoying - especially when you’re trying to fall asleep with this buzzing sound...
