Not a good experience. When I arrived at the studio it had not been properly cleaned (filthy toilette brush and moldy shower curtian, unwashed plates, black hair in the kitchen, dust on the shelves, spots on the walls etc). In addition the door to the toilet did not close and the toilet keep running when you flushed it. Also, it was stated in the listing that there would be a separate workspace (desk and chair), but there was no desk nor chair. Since the studio is located on ground floor/below ground, it is very humid with quite a strong smell.
Also do your research about the area. It says that the studio is located in the heart of Montemarte, but it's in Barbes - a location that by many is considered unsafe.
It was also difficult to get ahold of the host who did not return calls.
On the positive side, the wifi connection is excellent and the self checkin/out was easy. Also there's a washing machine.
