So, the stay did not start out very well. My wife and arranged to meet at the flat at 15h50. We arrived 5 minutes late due to not knowing exactly where to go. Upon arrival we were not greeted by the owner, but a friend of his who was quite rude. The first thing he says is that I was 45 minutes late and he nearly left us. I laughed as I thought he was kidding and he said that he was serious and wondered why it took so long. He was quite demeaning while presenting the apartment and left us not feeling welcome. Besides that, the apartment is below average. I understand that Paris is one of the most expensive cities in the world, but the price paid for the quality of stay at this flat is not worth it. It is musty, has mold and humidity problems, and all of the drains are clogged. We had to shower quickly to avoid water filling up the basin and spilling over to the floor. Finally, the flat looks directly into the windows of other flats so you must keep the curtains drawn to maintain any privacy.
The good points are that the neighborhood is a good one with lots of cafes, pubs, and stores. It is a pretty long walk to the metro, but it is on line 1 which goes to most tourist locations.
