We stayed for 10 nights in the apartment and had a great time! The apartment is in a great location in Le Marais district with so many cafes, restaurants, grocery stores, bars, boutiques, and parks nearby. The Metro is about a 6-minute walk. My husband and I stayed with our two boys, ages 6 and 9, and we were able to make the space work. They happily slept on the pull-out soft bed and we in the bedroom. There is a lot of closet space for storage, fast wi-fi, well-equipped kitchen, a washer/dryer combo, and large bathroom and shower. The entire apartment has been remodeled somewhat recently, so it all felt "newer" but also somewhat like living in an Ikea showroom.
My one piece of advice is: MAKE SURE YOU HAVE RECEIVED AND FULLY UNDERSTAND THE CHECK-IN INSTRUCTIONS BEFORE ARRIVING! The four of us had been traveling from Los Angeles for 18+ hours, and when we got to the address near midnight, I realized all the instructions I had received were "The key is under the mat!" I had never been to Paris so didn't understand that this is an apartment with multiple levels and multiple coded-doorways and hallways to access. We arrived and only made our way inside thanks to the kind owner of the restaurant next door, who knew the codes, and was so worried for us and our children and not being able to get in at midnight. "Pierre" did respond to my texts that night when I asked how to get in, and eventually we found our way to the apartment front door.
This place is great especially for couples and small families who want to spend most of their time outside and exploring Paris; then it is so nice to return to the apartment, watch some Netflix, have a glass of wine, and unwind. Enjoy!
