I had a perfect stay at Marie-sophie's flat. It's very easy to walk to a lot of museums and its also close to three metro lines. The flat itself is really bright and clean! There is a decent bathroom, a kitchenette with microwave, stovetop, and mini fridge, and a small writing desk. The view of sunsets out the window is incredible and it was really a joy to live here for a few weeks. Marie-sophie is SO friendly and helpful and interesting. She knows a lot about Paris and especially about art. I can't recommend staying here enough!
