Jen is a great host, she really cares of about her guests, we feel it once we step into the apartment. Whether you are a first-time visitor or not, do take Jen's advices about staying safe in Paris, and read through the materials she prepared, pay attention to the pocket picker information. We had a great time in Paris (first timer), we only give the apartment 4 out of 5 stars because of something not in Jen's control. First, there is no elevator in the building, so if you have a small child that you have to carry up and down, or have a big and heavy suitcase, do consider the steep and narrow stairs to the 5th floor. To be honest we were in shock when we see the staircase, only one adult can fit in it and I almost slid a few times had I not holding the handrail. Second it was the mosquitos, we encountered quite a few each night and it was inconvenience to say the least. Even with this, we still recommend Jen as a host.
