We had a great time at Jean-Charles' apartment. It was comfortable and central to everything. It was very clean . We even managed to buy food at the St Antoine market which is right on the doorstep most days. The range of produce is excellent and allowed us to eat at the bnb instead of paying for expensive meals constantly.
If there was one problem I had it's that the front door to the building is extremely heavy.
All up it was a great apartment and highly recommended
