We stayed at Rene’s place for over a month and it was a pleasant stay. The apartment location is perfect. You can get to any major attractions or popular restaurants in 20-30 minutes, and you have the RER B train directly to both the train station and CDG airport. The apartment is well equipped and have everything that you may need. The only caveat is that the apartment is in a very old building as you would expect in central Paris. So the stairs could be narrow and old. Other than that, it was a perfect apartment and I would definitely recommend it.
