Kat's studio was a great experience. She is the most friendly host I have ever had at AirBnB. Check-in was easy, even with my delay due to terrible traffic jam. The apartment doesn't look cold like many "professional" airbnb places in Paris. You really feel at someone's home, bringing back that real airbnb soul. At Kat's place you don't feel in Paris only when you are outside, it's totally Paris inside too, with her library with many books and other details. Bathroom and kitchen are brand new. The building is nice and well maintained. The location is simply amazing, many metro stations to choose from, walking distance to many great landmarks and restaurants. In less than 100 meters you can choose from fancy sea food to simple and traditional crepes bretonnes.
