We stayed in Pierre Marie's place for the start of our honeymoon and it was perfect - very clean, great amenities and in a great location. You can walk to most key attractions in 20 minutes, or there are three metro lines within a short walk. You are also just around the corner from Le grand epicierie and au bon marche for fancy shopping.
The place itself feels quite luxurious for Paris. More than enough room for the two of us with a very comfortable bed, easy to use kitchen, modern bathroom and lounge area.
The photos reflect the apartment - if you like them you will love the place!
