It's a very nice flat located in Montmarte area. It's just a nice home, with high quality stuffs showing the good taste of the owner. Matthieu was very responsive and helpful, and very very flexible. The court yard itself is very quiet and the street which the windows facing to is also comparatively quiet (despite you can see your cross street neighbours if both don't close the curtains... part of the fun of living in Paris). Just keep in mind that if you have heavy luggages or couldn't climb stairs much, the flat its at fifth floor without a lift, which is rather common for Paris flat renting I am afraid. Not much the host can do about it, and other than that it's nearly perfect.
