Séverine was traveling so we didn't get to meet her but her son Théo received us and showed us around the place. He was helpful and Séverine and her husband were always available to answer questions. Before booking I was very particular about the internet connection as I work from home a lot and she went out of her way to answer all my questions, which by the way was pretty decent at 1Mbps/8Mbps (up/down).
The duplex is very much like the pictures. It was clean, had spare sheets and very comfortable. It is about a 20 minute walk to the Eiffel tower, has multiple metros within a 8 minute walk and is in a very convenient spot. The house itself is airy and cool in the summer. It does not have a fan but we missed it only on a few very hot nights. The neighborhood is quite, has a supermarket close by and multiple cafes and restaurants. A particularly good one is the Le Volant Basque, a must try.
Overall we had a great time, enjoyed the place and would definitely recommend the place.
