Judith is a wonderful host! She definitely cares about her guests. Everything was great, except one thing:
5 floors of STEEP stairs!
Be aware of this fact when you book. For just 2 days it was okay for me, but not everyone will feel comfortable climbing these stairs several times a day...
Other than that, the apartment was worth it. 30-minute walk to Eiffel Tower, 3-minute walk to subway. Very nice host :)
