Thank you Lucie!
We really enjoyed our staying in Lucie's apartment. We are an young family with a son 2 years old.
It was comfortable to live in a such typical French apartment where everything reminds you that you are in Paris - a lot of handmade things, pictures, antique furniture, beautiful forks, spoons and plates, and even piano :) Lucie left fresh flower for us and some drinks.
Also it was so kind from her side to let us use a plenty of guides, brochures and books about Paris and things to do there. It was helpful despite of we were ready with our own plan.
Communication with Lucie was extremely great and fast! She contacted us in advance and provided all information, answered all my numerous questions. We had flexible check-in and check-out time, that we were very happy about.
It worth to mention that the apartment is located great - everything is in a walkable distance - you just live between main sightseeings :) We went across Paris whole day and it was easy to come back to apartment to rest a bit. Metro station and river boats are very close, so you can reach everything with transport if you do not like to go for a walk a lot.
And the last thing (advice for families with children)
1. If you have a pram, take a lock for it. Apartment is located on the 4-th floor, so it is possible to lock a pram on the ground floor. We had it and we were calm about a pram.
2. Regarding apartment itself - just in case put all breakable things out of reach and keep your eyes on your kid all the time :):)
