Thomas and Patrick were fabulous hosts. They responded quickly to our every need (and we had many minor crises that they helped us through). Patrick made arrival and departure as easy as possible despite our tight schedule.
The apt is fully equipped. Washing machine and dishwasher were a great asset and when we figured it out, they worked well. An instruction booklet would have helped us find hair dryer, use stove without texting Thomas, etc.
My only caveat is if you are older or mobility impaired, the bathroom will be problematic or impossible. You need to climb steps up to access bathroom, and climb down into a sunken tub to bath or shower.
Location, while not as charming as some other parts of Paris, was very practical. Bus and Metro--several lines nearby, across the street or a block or two away. An easy walk to the Marais, which is super charming. And a longer, but enjoyable walk to the Louvre, Notre Dame, Pompidou Center.
