This very unique studio is great for a couple. Is is very quiet specially at the end of the day and at night, so it's really good when you come home tired from the long walks around Paris, also the bed is comfortable.
There are couple of nice place to look around (Rue Mouffetard is a few minutes away by walk).
Access to bus and subway is also good and will bring you at almost all major touristic spots without having to transfer.
You can walk to the Luxembourg Gardens area within 10 minutes or so. Notre Dame area is also not so far.
There are multiple small and bigger groceries store around so that's very convenient.
The studio offers everything you need for a long stay, but make sure to ask for what to bring (shower products, laundry soap etc) or just buy it when you arrive there.
The team is great and are available to help you if needed.
It's a bit expensive but if it's your first time in Paris and budget is not a problem, we recommended it.
