We, a family with two children(1.5y.o. and 4 y.o.), spent 3 days in this apartment. The location is very nice with a few local shops and cafés and restaurants. The area was quiet in the evening. There are several metro stations near by(it was less than 30min to the Louvre). The apartment has everything one might need during the stay. Additionally we requested a child cot bed(+10 euro/day).
Cédric was available per phone and was ready to help and clarify any question.
We can highly recommend this apartment and Cédric as a host.
