Staying at Johann's place was simply fantastic. My girlfriend and I only arrived in Paris late in the evening and yet Johann was kind enough to wait for us and to show us around the apartment as well as recommend some locations in Paris not really known to tourists.
The apartment itself has everything one needs for a great stay. Great bedroom, a coffee machine, clean modern kitchen, cozy couch, a TV, and a really fantastic little patio where having dinner is just amazing.
Communication before, during, and after the stay was fast and efficient, so any sort of issue or questions could be cleared up immediately.
Location was just far enough from the center to be quiet at night but also close enough to make travelling convenient.
Overall, I would recommend this place to anyone seeking a stay in an apartment in Paris, you really can't go wrong with this choice!
