Frédérics apartment is small, but lovely. It has everything you need for a relaxed stay in Paris. It's located very well in the heart of montmartre close to nice bars, restaurants and supermarkets. It has good connections to the subway and bus. The communication with Frédéric was really good; he always answered very quickly and informed if we had arrived well. Frédéric was ok with the fact that we brought our 7 months old daughter (we brought everything we needed for her), so this is a big plus!
I definitely recommend the place.
