I stayed in this beautiful flat for more than 2 months, and I really enjoyed it. It is clean, bright, peaceful, comfortable and modern with everything to cook in the kitchen and a very performing wifi.
I could not really take profit of the restaurants and pubs of the pedestrian area or the theaters and museums next to, but I loved the calm and vibe of this neighbourhood, the clothes and high quality food shops, and above all, the parks and gardens 5mn run (Les Halles, Palais Royal and les Tuileries).
The location and this place are just amazing and Nathalie is very welcoming. I do recommend !
