Pros:
-FANTASTIC location
-Fun decor and space, reflecting Notre Dame
-Easy check-in
-Nice communication from host
Cons:
-Not enough shampoo/soap/towels (minor issue)
-Lack of privacy in bathroom upstairs (a more opaque curtain would solve this minor issue)
-Very narrow stairway (clearly described in listing). It was fine for us, but if you have trouble with stairs, are a larger person or have lots of luggage, it could be an issue.
Overall we were quite satisfied and happy to be staying in such a great spot in Paris.
