Catharine's small but comfy flat was a great base for me and my son during our 5-day visit to Paris. It has all the basic comforts and is in an excellent location. The metro is two minutes walk away and there are many groceries, cafés and other shops nearby. The area is not overly touristy so it has an authentic Parisian, and ethnic, feel. The canal St. Martin is nearby as well. We were able to walk home all the way from the Louvre, though it took a couple of hours - including stops. The beds were comfortable (Ikea) and everything worked well.
Catherine was available by email and I appreciated her quick response to my queries. You should be aware that there is no fan or window in the bathroom (it is adjacent to the kitchenette) and no coverings for the windows in the main room.
I recommend Catherine's flat and would definitely stay there again!
