Was a perfect homebase for our family of four (with a tween and a teen). The 10th is such a cool residential neighborhood while also being a quick metro ride away from pretty much everything. We never took a taxi once. (Though definitely got a work out carrying luggage up/down metro stairs).
The apartment comes as advertised. One thing that I didn't see in previous reviews is that one of the bathroom's rain shower head is super luxurious for anyone used to mediocre water pressure while traveling (or at home).
Canal Saint Martin is one of the best places in Paris to enjoy an afternoon or evening and it's only about an 7 minute walk from the apt. I highly recommend walking up and down the block and checking out the restaurants/shops so that you can stay close to home when you need a break from trekking around town.
