I had to cut stay in Laurence's place short (originally booked for one month) after I saw mice in the flat. The house was left super untidy, it looked like someone left it in a rush before I arrived. It was full of the host's stuff, in the closets, under the bed, etc. There was even a broken arm chair put randomly by the bed. It was not possible for one to settle for a month. The place was also very dirty, let alone disinfected. I had to clean all surfaces and utensils prior to use.
The quality of sleep you would get isn't great as well, the mattress is too thin, it's too bright in the morning and on the first floor facing a bus stop, so you would hear all the street noises. The is no sense of privacy in the flat, as there is no curtains except useless paper thin one in the bedroom, people on the street and neighbors in the facing buildings get a complete view of the inside, even of the shower (which has no curtain as well). There was no coffee, nor any sort of coffee machine. Many of the products left in the kitchen were spilling, sticky and already expired.
However, the flat looks better than the pictures, the windows are amazing and make it so bright. The décor is originally nice, had it not been worn out. The location is amazing!! Right in the heart of the Marais. It could be suitable for a very short stay, but definitely not for a long one, unless the host decides to make some improvement.
