Great location in Montmartre. The bed is very comfortable and the apartment is quiet. The pictures are accurate. I used the kitchen for breakfast - ample refrigerator space and cook space. There were earlier comments about the size of the bathroom. In my experience European bathrooms are smaller than American bathrooms - it is part of the cultural experience and did not negatively impact my stay. Good hot water, good Wifi.
The location is fantastic. The Metro line is a block away, 12 line I recall. Gare du Nord and Gare d'Est are fifteen minute ride/walk. I went out each morning for a fresh baguette, fruit, and cheeses in the neighborhood markets. Awesome!!! Wine as well. Several banks with ATMs around Abesses Metro station. Safe area, but I stayed away from the overt tourist areas like base of the funicular and square near Sacre Couers - no issue, just prefer to be in the working neighborhood areas.
There are plenty of small family run restaurants just around the corner worth your time: d'Artiste, Taverne Montmartre, Chez Plummeau, etc. Good food, easy walk. I had morning tea sitting at the table looking out the window across the rooftops - if you enjoy that as I do then this place is great.
It is a small place, but I enjoy the intimacy and immersion into the neighborhoods as part of the vacation experience. It allowed me to get away and relax.
