We are a CA family of five, first time in Paris with the kids, if you want the long version, read on, for the short version: BOOK THIS PLACE, amazing all around.
Long version:
If you ever visited Paris (and Europe in general) you know that apartment sizes are not their strong suit. usually, it's small, very small, so when planning to travel with our three kids, we wanted to make sure we pick a place that is comfortable.
Layout and Rooms:
This place is definitely BIG by European standards, and very comfortable in California-condo-size-standards. If I had to guess I would say 1,000-1,200sf.

There are three sleeping rooms, each with a nice big bed (I believe all queens), each has a sliding door to a balcony, a ton of light and air at night. The condo has two bathroom showers, and one separate toilet room, yes, the bathrooms do not have a toilet attached to them, these are rooms to take a shower only. Worked great for us since most teens like to spend time IN THE SHOWER and not on the toilet :-)
The living room has a nice big balcony with a table and chairs so you can eat in the open air, a good size kitchen with everything you need, no TV anywhere in the house, and a ton of books.
No TV?! no need, the internet speed is FAST, over 200mb/s, and everyone was on their smart devices Netflixing / Prime Video away with no issue. worked out great.
Location:
Location was the crown jewel of this abb. You are close to everything. 60 sec away is a main (quiet) road with a ton of restaurants and multiple bakeries. it's an easy 5-7min walk to multiple Metro stations (very easy to use, give it a try) which will take you anywhere you want (Eiffle, Louve, Arc of triumph etc) and the neighborhood is quiet and welcoming.
Moving around:
Don't give up on the metro, it's awesome. We are from CA so this was new to us as well, but after your first ride, you will feel like a pro, it's by far the best way to get around the city, especially when Uber is very unreliable in Paris. You can wait 10-15min just to get canceled on. Download the app "Paris Metro" (it has a red icon, free) and it will make everything much easier.
Check-in/out and communication
Check-In instructions were very easy to follow, the condo was SPOTLESS, clean clean clean. I am a Super Host myself, I know clean when I see it. very nicely done.
All communication was done via the abb app and we got answers in minutes, sometimes even faster, very much appreciated.
All in all, this is a great abb, great size, great location, professionally managed, and perfect for families.
Have fun and enjoy Paris, there is really no other city like it :-)
