As Ebé has noted in her Airbnb listing and as other reviews have noted, this Airbnb is small in size (approximately 150 square feet) - but what it lacks in size, it makes up for by being in a great location with good food options and number of sightseeing locations within a 30 minute walking radius distance (example - Louvre Museum is a 23 minute walk). Overall I would recommend this Airbnb and I have provided additional information below.
The Airbnb has a sofa double bed fold out that can fit two adults max - note that the bed takes up at least 70% of the space when opened up for use. There is a small kitchenette with a mini fridge which was a really nice option to have. There is a small closet in the corner for hanging clothing and another cabinet with kitchen utensils and extra toilet paper.
Towels and body wash are provided for the Airbnb use so make sure to bring your own shampoo/conditioner. The shower and bathroom is clean but note that the shower is less than 3 feet by 3 feet in size - this may be too small for some individuals.
The window opens up to the courtyard which was very pleasant. The WiFi worked fine and accessing the condo was easy with the key that was provided.
One final note to add is that Ebé was an amazing and friendly host - she was great with communication and let us check in earlier which was very accomodating.
Overall, I would recommend this Airbnb if you can work with the small size. The location makes up for it and you'll be out exploring Paris most of the time anyway.
