We had a really nice time at Sébastiens place. The room in the apartment is clean, cozy and the architecture is awesome. We had the fealing of not just being a visitor in Paris, more like being a local. The neighborhood was also very friendly. We were greeted by the neighbors all the time with a smile.
Sébastien is a super friendly host and will help all the time. We'd like go there again next time visiting Paris :)
