Joanna is awesome! Leading up to my stay, I had a lot of questions and she always answered quickly and thoroughly. When we arrived in Paris, the apartment wasn't ready yet, so she allowed for us to drop off our luggage at her office until check-in time. This was huge for us and one of the main reasons I chose her apartment over others.
The apartment is in such a great location. But with that, comes LOTS of street noise. So like others have suggested, make sure to bring earplugs or a noise machine to help you sleep. The apartment above Joanna's was extremely noisy a few of the days at 5am, but earplugs should help with that. I brought a sleep mask based on some of the other reviews and that worked perfect for any light that may have been coming in from the windows.
There were 4 of us girls staying in this apartment and it worked out great. We setup stations and would just rotate getting ready. Shower is small but works great with great heat.
Highly recommend!!
