This was a great experience for my wife & I as our first exposure to airbnb. As advertised, our local host Reem was the perfect concierge. We needed to find a hairdresser, she was able to direct my wife to an excellent salon. We had some issues with SIM cards for our phones & Reem was able to cure them almost by magic.
The pictures on the website surprised me with their accuracy compared to the actual apartment.It was a nice treat to have a kitchen to use.
Location near the Chatelet RER station couldn't be easier for arrivals from CDG.(Unfortunately there was a strike and we ended up taking a taxi but that's travel in France!) There are many nice cafes a short distance from the apartment.
We had booked 2 stays a week apart but ended up only staying four nights as we wanted be on Champ Elysee for our last nights in Paris. I cancelled the reservation but have yet to receive the credit.
Only a few minuses. As has been mentioned by others, the apt is 5 floors up by stairs so heavy bags can be a problem. There was minimal storage space in the apt for our clothes.
All in all, if you're travelling light this is an excellent opportunity.
