Great location! The apartment was very basic but in the perfect location for walking. The Louvre, Seine, Montmarte, Opera etc are all within a 20 minute walk. There's also a really good metro station close by which was handy as it was line we needed to get to La Seine Musicale!
The area is a bit mixed, some dodgy places and some really beautiful spots. I wouldn't feel comfortable walking there alone but with my husband it was fine. Brasserie Dubillot is really close by and absolutely fantastic!!!
