I recently stated at Pierre's studio for five night's and it was a lovely experience. The apartment itself is very modern and in a perfectly located neighborhood in Paris. The location is quiet, safe, with several metro stops nearby, and is easily accessible from all Paris airport and train stations. Pierre himself was an excellent host and was kind enough to provide an extremely thorough listing of nearby recommendations per my request. Hosts like Pierre are what is best about Air BnB and I would be happy to recommend his apartment to anyone.
