Having myself lived in Paris in many studios or apartment, this studio is definitely one of the most beautiful place I've seen in Paris!
This studio was clearly newly renovated, and it's now nicely decorated and welcoming. Hardwood floors, stylish little kitchen, very comfortable bed and pillows, water is hot and water pressure is good, very clean, etc.
Simon usually lives in the studio so be mindful that you won't have access to the wardrobe or the bathroom cabinet (although it absolutely didn't bother us!)
The street can be slightly noisy, especially in the midst of the summer with the windows ajar, but nothing crazy either (just Paris being Paris).
Location is perfect, there are a few subway lines a few minutes away, and the canal is within walking time too.
Highly recommended, we'd come back in a heartbeat! Thanks Simon.
