I had a lovely stay at Frederique's charming studio in the heart of the 18th - still a lively part of Paris but far quieter and away from the crowds of tourists. It was the area I wanted to stay in, and her place is a 1 minute's walk to a metro station making it even easier to get around Paris. You're about a 10-minute walk from Sacre Coeur, a 20-minute walk or so to Moulin Rouge, and within an hour of relaxed strolling, you can find yourself in the 2nd arrondissement. If you enjoy walking as much as I do, this is a very good spot to be based. (If you like gin, there's a craft gin boutique just up the street you must check out).
Her apartment also faces the building courtyard so the evenings were quiet. I had everything I needed for my stay and Frederique was always very easy to get a hold of. I ran into a bit of an issue during my check-in but this was due to an error on the cleaning company side and Frederique was very active in trying to solve the issue. I'd happily stay here again!
