Awesome place. I’d book this again instantly for a Paris stay without looking anywhere else.
The location is highly central in le Marais and minutes to the airport RER, and other main transit lines. Even so it’s totally quiet on a side street at night. Immediately around you have great cafés, restaurants, bars both casual and upscale. This is where a lot of people want to live in the city.
The place itself is just very cool - Emmanuel has great taste and gives a wonderful sense of place. The layout gives a lot of room for living/kitchen and the bed has excellent circulation. Good light exposure front and back.
