All in all a good stay. Positive points:
1. Great location, you have a ton of shopping, restaurants, groceries, and public transportation right out the front door. Close enough to walk comfortably to the river and Notre Dame. An hour walk or so to Eiffel Tour.
2. Christine was a great host. Lots of communication. She was also very sweet leaving a gift since I was in town celebrating.
3. Christine made good when we had an issue. Due to a issue in the neighborhood the building we were in lost internet for our stay. We received compensation for this without having to ask.
4. Place was everything you need for a short stay.
5. Price was very good based on my comparison shopping.
Negative Point:
1. You are close to the action in this flat. For my wife and I, it was too close. We were visiting from a quite suburb and the noise and at slightly bothered us. Some of the area bars played music and the faint din of bass could be heard. Also, they emptied bottles to the recycling well into the late hours of the night. For some this level of noise may be expected, even wanted, but for us it was a little annoying.
Summary:
I would recommend this flat to any budget traveler, or someone who wanted to be in the middle of the action. I would also stay here again.
