What a perfect apartment for our Paris stay. We stayed for 4 days to discover Paris. The location is between two metro stations so you aren't far from much. The island of Louis is very cute and quiet. Some bakeries to get your fresh bread and pastries as well as great brasseries at the end of the island for lunch or dinner. There is a small grocery store as well 3 minutes away to get anything you need. There is the famous ice cream location nearby as well.
The views of the apartment are much better than expected. The images on Airbnb don't do it justice. The way you can wake up every morning with beautiful views and the sun shining on the buildings across the Seine. The host was very nice and greeted us with water, juice and great guidance on the city. We enjoyed our stay very much and it is such a great place. Only thing to note is the five flights of stairs. It might be tough with lots of baggages or by doing it multiple times a day. We would definitely come back once possible!
