Lovely quirky flat with a ton of character. The decor is vintage and eclectic with a lot of soul. As for the location, I did not know about Ile de St.Louis and it is quite amazing. You cross the bridge from the busy Marais and arrive in a little quiet haven. The island itself is like a little village in the middle of the hustle and bustle. The location could not be better in my opinion. Marie is communicative and responsive. I stupidly left something there and she immediately offered to post this to me which is a lovely thing to do. In all I would thoroughly recommend this place for a wonderful Paris experience.
