A very nice stay.
Great proximity to the metro stations and no shortage of cafes and restaurants to see.
The neighborhood does not seem the most touristy, but that was a positive for us.
The staff was very nice and accommodating. All spoke English very well in messages and correspondence, which made the whole process a breeze.
The street could be a little noisy at night, but the room is quiet and has blackout shades of you're in need of resting off jet lag, as we were.
The rooms are small, but larger than we expected, given the nature of Parisian apartments. Bathroom sink is absolutely tiny, so don't think about using it for more than washing up. Our shower seemed to have a little bit of a problem with the door not going all the way to the floor, which resulted in the need for a towel at the bottom to keep the rest of the bathroom from having puddles, but it was not a big deal. Tight spaces will have their quirks.
Overall, very happy with our stay.
