Vanessa & Viet's home (which we stayed in for 14 days) is a beautiful petite oasis inside Paris. The house is beautifully decorated, looking like something out of a magazine, with a picturesque view on the back side. Metro lines that take you to the major sites, supermarkets and a bakery (Au Blé d'Or, fantastic baguette; a closer bakery was closed in August) are within walking distance. The main bathroom is great, with a normal sized toilet bowl, separate large shower section, good lighting & large mirror. Taking your breakfast in the equally picturesque garden comes highly recommended :-)
We enjoyed our stay and would recommend renting the house if available, but here are some reasons it might not be for you: The stairs are not only steep, but also quite narrow, especially the ones leading up to the 2nd floor, which I could only traverse turning sideways. There is no convenient bathroom on the ground floor (kitchen/living area), you either need to go to the small toilet in the cabin through the garden, or upstairs. The en suite bathroom in the main bedroom is also small, and has no door. The portable ac is in one of the childrens' bedrooms on the 2nd floor, not in the main bedroom on the 1st floor (We decided against trying to move it down the narrow stairs, also because we did not want to keep the 1st floor window permanently open during the night (see below)), and in the hot summer month (we had 36C max in August) the house gets quite warm, and it took until 3am until you we could actually get it to cool down by opening the 1st floor bedroom & staircase windows. Outside the bedroom window there is not a lot of traffic, but it does not cease during the night, and the noise a passing vehicle makes when the windows are open is quite loud. At one point the neighbors living next door had a techno music party until 5 in the morning, making it very hard to sleep (we were told they "had something to celebrate"), 2 days later the music stopped at a reasonable quarter past 10pm. The toaster was semi-broken, either burning the toast or only warming it up. We also wondered if it would not be quite easy to break into the house: There is no alarm system, and if someone could make a hole into the glass sliding garden doors leading into the kitchen, he could just open the door by turning the handle, since it cannot be locked. It also felt like someone should be able to scale the bedroom window relatively easily, especially in the city that invented parcour. The last thing is that the grass in the garden is artificial, which means you will get an electric jolt when touching a conductive surface when not walking barefoot (however it is high quality and nice to walk on). We hope this feedback is useful for any future visiteurs, bon voyage & enjoy Paris :-)
