The apartment is in a great location. Many tourist attractions are just a short walking distance away, metro stations are near, there are plenty of bars, cafes, and restaurants in the neighborhood etc.
The apartment itself is cute and probably more spacious than many others in this price range. People watchers certainly appreciate the opportunity to observe the life of Parisians from the bathroom window. I did hit my head on several occasions because the apartment is on the top floor and has a sloping ceiling, but if you are not as clumsy as I am, you won't have any problems with it. It's also true that the stairs seem a bit daunting at first, but you get used to it very quickly and learn to appreciate the much quieter and more private space on the upper floors.
The communication with Sohée was really easy and effortless. She responded quickly, was there to greet us and left us with no stress whatsoever. Would definitely stay there again :)
