A fabulous location within walking distance to Rue Cler and the Eiffel Tower. We thoroughly enjoyed our stay, and found the flat to be modern and comfortable. The view of the Eiffel Tower from the loft was a very nice surprise.
The only drawback was a slightly dangerous metal spiral staircase from the main level to the bathroom and loft. It is steep and has a sharp edge. Both myself and my 23 year old son cut our feet on the staircase :/ which resulted in a lot of blood and some discomfort walking. My son sliced his heel far worse than my toe, and we have been to a dozen pharmacies looking for the right bandages to make the trip more comfortable for him.
All things considered though, the flat really is lovely and in a terrific part of town. We travel to Paris often and wouldn't hesitate to stay here again -- we'd just know to only go up and down the stairs wearing shoes. Once we had that part figured out, it was no issue.
