Ach's place is very spacious and perfectly located in a quaint block of apartments just around the corner from the Saint Germain metro station.
This flat provides all that is needed for a no-frills, low-touch stay. I found the kitchen to be pretty unuseful/outdated and there weren't any bathing products to speak of, but otherwise, the wifi is fast and the air conditioning is a nice touch. The apartment does have a bit of an intense smell from the perfume diffusers, which gave me a headache at times. I definitely got the sense that this place photographs well, but felt dingy after being in it for just a few hours.
Communication from Ach could be improved. They respond quickly, but nothing was communicated to me prior to regarding tips/tricks for the area or what to do in case of emergency. Additionally, a false address was provided upon reserving and it wasn't clear why this was the case.
