Good things are that it was an old classic apartment with flowery decoration, was clean, and was close to the convenient bus stop & only 10min walks to RER B station which directly takes us to CDG and Orly airport as well as to the city centre. Also the host, Brigette could communicate with me well in English.
However, for my family, it wasn't a good choice personally.
1. Although it was written that this option includes one bedroom and one bathroom, I did not know from the instruction that we would have to share all other areas with the host who works there. It was not very comfortable especially for my parents who cannot speak English & and who needed rests in the middle of days when the host is there. Also, we got complained that we moved things while we stayed (we moved flower vases to have a space on the kitchen table for our dinner, and thought to put it back afterwards)... So overall, we did not feel that we really shared the living room when the host was there - which is from 9AM to 9PM. We did not feel homey there.
2. Well, when I arrived, I mistook the host's neighbour as Brigette (the host). So I asked her if she was my Airbnb host. Then Brigette came down and saw this, and complained a lot to us that we disclosed about Airbnb to her neighbour... But how could we know that it was a secret that she is doing Airbnb in the building... It wasn't a pleasant first encounter especially for my parents who just arrived in Paris after 12-hour flight.
3. After a check-out time, it was difficult to keep our luggage at her place during the day comfortably - when there was the next guest. But Brigette tried to compromise us to keep it for 3 hours at least.
Overall, I recommend this place for young people who want to experience classic French building and also who do not mind sharing areas with others. There is a great park near there and it is a safe place. But for my parents in their 60s, it was absolutely not a good option- they preferred 3-star hotel (with a similar price) to this one for the reasons I mentioned above.
