Mary Ann's apartment is situated very centrally on the edge of le Marais. There is a metro station literally outside the front door so it's uber convenient.
There are also 2 supermarkets super close by and a gorgeous bakery at street level.
The apartment is quirky in its layout. It suited our family (2 adults, 2 young children) well. We all slept soundly.
We enjoyed our stay here and would recommend it.
