First, the host - she was great. Answered all our questions as soon as she could and made sure we were taken care of since she was out of town. She provided all necessities and made sure we found everything we needed. Her associate, Pierre, was also great. He got everything ready when we got there, walked us through everything, and made sure we were good before leaving us.
The apartment - great one bedroom, airy, clean and just enough for what we needed. The sofa bed was comfortable. There was more than enough space for the four of us. It really exceeded our expectations.
The location - was great! It is in what they called the fashion district. There are a lot of brasserie around the area if that's what you're looking for. It is walking distance to Rue Montorgueil which is a street lined with restaurant, cafes, and stores. There is also a u-express (like 7-11 but better) around the corner which was convenient. The Louvre was a 15-minutes walk from the apartment.
Overall, our experience turned out great and her apartment will be on top of our list next time.
