This is the most amazing loft! The design is outstanding and the location is great. The loft is perfect for two people and is very spacious. You can tell that the owner cares about their space very much because every single piece of furniture, design, art, and object is extremely well thought out. The space is very comfortable, although slightly warm, but there are plenty of fans and a great ac unit in the bedroom (and you need to remember that you are on the top floor).
The loft is close to everything - you can easily walk to the Marais, or head to the canal to hang out at sunset with a bottle of wine. There are also plenty of places to eat and drink nearby, along with the organic market just around the corner that has all the essentials.
I hope to stay in this loft every time I visit Paris from now on.
