The apartment is amazing! The elevator was clutch for when we arrived with our luggage. However, it was not operating when we departed (not the fault of the host - just giving a heads up that you should not solely rely on it just in case that is a big sticking point for you.).
We felt very safe and the neighborhood was amazing. The apartment is very close to several metro stops and is very walkable to le marais! Highly recommend. Would stay here again and already miss it.
