Amazing location of the apartment, walking distance to several Metro lines and the train to both airports. You could certainly walk to several places such as the Louvre museum and Notre Dame for example. Hundreds of restaurants, coffee shops, creperies and bakeries around the apartment area to choose from, including a handful of supermarkets for some grocery shopping as well. Very live neighborhood all day and night.
The apartment was perfect for us, a family of 4 with small children, a fully equipped kitchen and a washing machine. It had everything we need for a very comfortable stay. As she and others have already mentioned, the stairs could be a little tiring for some but have to say after a couple of days we had already gotten used to it and we did not mind them, specially after too many nutella crepes, we needed to burn additional calories.
And last but not least, Gam was an amazing host. She was very prompt to answer questions and providing information on our arrival. Had the pleasure to chat in person with her on the last day as well. Definitely will look for this place again when we come back.
