Wonderful place. I will definitely try to stay here again next time I'm in Paris. The neighborhood is really fantastic. Less busy than some of the more touristy areas, and full of wonderful shops and restaurants. While walking around the 9th, we didn't feel like we were in a mob of tourists, more like we were joining other Parisians going about their day.
Frederique's apartment is wonderful. Really nicely laid out, with a great kitchen area, very clean, and the great art and decorations made it extra fun. Frederique was also an excellent host, gave a thorough apartment tour on arrival, and shared some of her Paris recommendations.
