Strictly non smoking flat.
Romain has a lovely apartment, which was very clean and comfortable. The location was great (very close to metro spots and the canal). It was a little noisy with the windows open (there was also a music festival going one of the days we were there), and we would have appreciated a fan. Overall we were very happy and would stay again :)
My stay at Romain's was great. I love the neighbourhood and the apartment is just behind Canal Saint Martin. Great spot to hang out, but also to just walk down to the Marais. If you are into running, you will appreciate the canal itself and the park of Buttes des Chaumont nearby. The apartment is super clean and comfortable. Curated in the details. Highly recommended!
