I had a great experience at Studio Wattignies! Nadia, the host, is a quick and clear communicator and the studio was exactly as promised. This isn't in the heart of the main Paris attractions, but there is a Metro entrance on the next street so you still have easy access to the city. I liked being able to cook and store food for myself since I had a longer stay, and eating out 100% of the time gets pricey. Definitely would recommend for Paris visitors.
