My family and I (4 adults) spent most of a week in this apartment in early June. The best thing about the apartment is the location. As many others have said, it is centrally located in Paris and within walking distance of many sites, including Notre Dame and the Louvre. The apartment is also quite large and a good value for the price. There is common sitting room with a dining area, a small kitchen, two bedrooms, and a bathroom. One bedroom has a pullout sofa and the other has a double bed. Both bedrooms and the common area are nice-sized for an apartment. The bathroom is also relatively large with a nice shower. Hand soap was provided and there was one bath towel for each person, plus two hand towels.
When we were there, the temperature was in the 60s and 70s, so we were very comfortable without air conditioning. You do need to walk up a flight of circular stairs to get to the apartment, which can be somewhat difficult with large luggage. The apartment has Wi-Fi which was very reliable, and we really appreciated being able to use the Wi-Fi to stay in touch with family back in the States. We had expected to be able to use the washing machine that is listed in the description, but it was not working. The apartment has a nice selection of books and some art on the walls, but it is an older apartment and could use some fresh paint. If you are used to staying in nice hotels, this may not be the place for you.
My communication in setting up our stay was with Laure, and she was quick to respond when I had a question. We flew standby, so I did not know exactly when we would be checking in to the apartment. Laure shared with us how to get into the apartment and where the key would be. My experience with other Airbnb hosts is that they come to meet with us to introduce us to the apartment and the neighborhood, and/or provide written directions or suggestions specific to the apartment and the neighborhood. Laure did neither, but I think she would have answered any questions if I had asked, and she did message me the night before we left to tell us what to do with the trash. We would have liked to know that the washing machine was not available before we arrived, but we were able to wash out some things in the sink.
The bottom line is I definitely would recommend staying in this apartment and would love to stay here again. The location, size, and price are major advantages. The drawbacks can be easily overlooked.
