The location would not be better. Notre Dame is just a stone away. Pantheon is close by, Sorbonne and the metro stations are all within walking distance. I walked from the house all the way to Eiffel Tower and it takes only an hour during which you can see most of the famous places in Paris throughout the route. Michel`s communication is off the chart and you feel like you are staying at one of your family members` houses. Just to manage the expectations, it is a cosy but small flat around 25-30m2. A good place for a family and two friends. Recommended.
