We just returned from a wonderful family trip to Paris (April 2015)! Nina was great to deal with. Responsive and helpful, even booking us a shuttle from the airport to the apartment.
The apartment is in a great location, easy to walk to Notre Dame and close to the Metro. It is in a busy area, with a lot of cafe's, bars, etc. Can get a bit noisy at night, as the clubs hoppin', but that is par for the course in such a busy city!
There were 6 of us, our family of 4 and my 2 parents. The accommodations worked well - (a little tight for 6) simple, clean, plenty of towels! One bedroom on first level for my parents and 3 bedrooms upstairs. Kids loved the spiral staircase!
Overall, great experience! Oh and there is a patisserie a few doors down, great for getting breakfast and snacks.
Thanks Nina, we had a great experience!
