First trip to Paris for a family of 5 (3 teenagers) - wonderful and charming apartment with all the necessities for a family vacation: wifi, room to spread out, washer & dryer, very accessible to metro and easy-to-deal with host and recommendations from the owner on nearby bakeries, chocolatiers, coffee, restaurants. We stayed for 5 days and Laurent was in communication with us regularly to make sure we had everything we needed. The views of the Eiffel Tower were great and the apartment is what I'd imagine true Parisian living to be!!
In no way meant to be a criticism, but more of a point of knowledge - this is in a quieter part of Paris so it doesn't have quite the hustle & bustle of a St. Germain-area. There are plenty of cafe's & restaurants within a 5-10 min walk (including Marzo which was a very nice break wood-fired pizza Italian restaurant) and a small grocery store and wine store to get all that is needed for a nice night in after a long day of exploring.
The metro got us to anywhere we wanted to be in 10-20 mins (and the metro wasn't as scary as some people make it out to be - you just need to be mindful of your surrounding while riding) - we felt safe the entire time.
