Roch was a wonderful host and we could not have been more pleased with his AirB&B. The photos depict well the lovely little studio apartment. The bed was comfortable, the kitchenette was wonderful, and the accommodation was very relaxing.
My wife and I truly enjoyed watching all of Europe's trains go in and out of the Gare du Nord station every day and night. The noise was not an issue as the windows were sound dampening. Also, seeing Sacré Coeur from our kitchen window was so cool!
I will leave one piece of feedback that the neighbourhood did not always feel the most comfortable to us as far as safety, but you're staying in Paris after all. The nice part was that the studio apartment is behind two locked building gate/doors, so we never felt unsafe once we were off the street. I'm mostly talking about possible pickpocket situations.
All in all this was a lovely space that fit our budget and our needs. It is very close to the Marx Doromy station. Roch is super quick to help with anything you need. He also is a very hospitable host who wanted our stay to be wonderful. He also speaks great English if you're afraid of not being able to speak French with your host.
