I really liked staying in this quartier with Dominique! You are close to touristy things in Montmartre but also distant enough that you can feel like a local. The downstairs café, La Chope du Chateau Rouge, is a great place, with friendly people, affordable food and drink, and occasional musical events. I'm so happy to have discovered it.
Dominique was often busy with her work but was very helpful whenever I needed something - she recommended a great place for pedicures just a few blocks away. She and Lisa were very easy to get along with and cooperating to use the kitchen and bathroom was no problem at all. I felt at home.
My only small problems were with the light in the upstairs room, it was a bit hard to read there, but then I have aging eyes. Also that carpet could have used a good cleaning, but I had a throw rug over it which helped when I did stretching exercises on the floor. But these are small things. The bedrooms face the court so even though this is a lively neighborhood, it was quiet at night, easy to sleep. There was plenty of room for hanging clothes and a shelf for other things, so storage was not a problem.
If you like a light-filled room and convenience of being on the same floor with bathroom and kitchen, you might want to choose the downstairs bedroom, especially for a longer stay.
I really liked staying with Dominique and would choose her place again!
