The apartment was exactly as advertised. Marry was a gracious host and quick to respond to any questions I had about the area etc! Good location— close to the metro line 1, which is the line most of the Paris attractions are close to. There is a lovely bakery just down the street where you can get pastries and bread, as well as nearby restaurants.
Please do note that, as described, the studio apartment is quite small. It is most suitable for 1 person or two max, which was great for me traveling alone for work.
