Marie's studio was my home away from home for two weeks. I could not asked for a better home and host. The studio is very well equipped, modern, very clean and comfortable, it has everything one needs and more. Great bed, small complementary tokens, attention to detail and prompt communication all make this Airbnb worthy of a five star hotel in the heart of Paris. Going up the stairs would also keep you fit, but you may think twice if you really have problems with climbing the stairs, as it is on the level six. However, I found this is a very small price to pay for a five star single accomodation. Next time I'm in Paris solo I know where I will be staying....
