Me and my boyfriend stayed for a month in this cozy apartment and we can confirm that he is perfectly well equipped for long season. Nafsika and her husband were great hosts, gave us tips on restaurants and markets around and other information that helped us during our stay. And we understand each other in a mixture of French, English and Spanish!
The only unexpected is that we need to get used to the shower, which has a time limit for the hot water (about 20 minutes, depends on the temperature used).
The neighborhood is quietly, there is a bus stop right in front and you can get to the metro station within a few minutes walk. It was our first experience with Airbnb and our first stay in Paris and we can say that we were very lucky to find her. We hope to return soon! :)
