I very much enjoyed my stay at Pauline's. Her place is furnished and decorated with great charm and likewise, Pauline's is incredible hospitality and warmth is a charm too. I felt very home and comfortable at her place and somewhat enchanted and inspired by the lovely and cozy atmosphere of her place. Pauline has also been nice and generous in making me get to know the neighborhood and her friends which gave me an unusual local experience of Paris, which I very much enjoyed.
A small side note that the studio you'll be staying in is sharing the entrance and corridor with Pauline's studio in a way that makes it feel more like two rooms in an apartment rather than two separate apartments. You do have your own bathroom and kitchen, however the sounds traverse very easily between the two places. Fortunately Pauline is very quiet and I had peaceful sleeps, but just I needed complete privacy, know that conversations could be overheard in both directions.
