I LOVE the location of this apartment. It's a big apartment and Claire is an awesome host. She walked us through check-in and made sure we had everything we needed. She was able to provide two baby beds for us! The metro is a short walk and if you walk up the street you're in the Latin quarter proper with great restaurants and fun atmosphere.
On a hot evening walk out and take a left and you'll be at the river in no time! Don't forget your bottle of wine and sit and enjoy a Parisian sunset along with the rest of the locals.
The park right across the street was great to walk through and fun for our kids.
I can highly reccomend this place if you're looking for your large group to stay in paris.
