Cozy place in a well-communicated area near Gare du Nord and Gare De L' Est with a nice view onto the roofs of Paris.
Disadvantages:
6'th floor with no escalator. (small luggage needed ; ))
No Wc in the bathrooms. There is one separate WC with access through the living room on the lower floor - so to access it from the main bedroom a walk through a small staircase is needed.
The lower bedroom has internal doors (like between rooms) to another apartment. When the second apartment was used (phone conversations at night or even steps on the wooden floor) it was difficult to sleep in our part, but in the end, there are more plusses than minuses. The mood is good and I recommend it.
