We stayed for 10 days, and this apartment really made us feel like we were living in Paris, rather than vacationing.
The unit is bright, with floor to ceiling windows looking over south Paris. The building is secured, and you are up high, so the view is good. You can even leave the windows open at night for that open-air feeling you see in all the architecture magazines. There is also a slimline air conditioner, if you feel you need it.
This is a small 1 bedroom, rather than a studio. The bath is nicely done, and the kitchen is efficient and worked great for us making meals after shopping the markets during the day. It has a full size refrigerator and small stove and laundry.
You are 1/2 block from the Saint-Jacques Metro station, and there is a Carrefore's City market between the Metro and you, for picking up anything you forgot while out and about. Just around the corner is a very nice little patisserie, and the vendor speaks great English.
Yannick was fantastic. He met us when we arrived to show us all the features of the unit, and was very responsive when we had questions.
We will stay here again when we return!
