Fantastic, all reviews are positive for a reason.
Our family of 4 had a brilliant time, we didn’t even use all of the space as the kids wanted to share the glass loft room.
The street is great with lots of restaurants, cafes and health food shops ( 3 vegan shops and a great butcher all within 20 meters, weird!).
Easy access to town about 15 euros in a cab from the champs de élysées.
We visited in January, i imagine it would be hot in summer as no aircon. Check in was great once we figured out the address.
Would highly recommend.
