Location Location Location. The apartment was exactly as described. Very chic and easily accessible. Everything we needed for our stay was minutes away, if not right on the street. Supermarkets, coffee shops, cafes, several train stations. The seine and Notre Dame were a ten minute walk away. And a quick uber ride the the Marais shopping district. The team was very responsive and available. As noted in other reviews, the elevator was very small, and can truly only fit one adult at a time, but it's wasn't a bother, more humorous than anything. Only real issue was there was construction being done on the roof while we were there. It sounded like they were jack hammering right into the apartment. I'm not sure if it was a long term project or just a few days coinciding with our stay. They start very early in the morning on weekdays (before 8 one day) and go all day, so sleeping in was not an option. Luckily we got our days started pretty early, but it wasn't a pleasant way to wake up in the morning.
It was not a reason to not stay in the apartment, as it was fabulous otherwise, but certainly worth noting.
