This is a very cute apartment in a conveniently located building. The warnings about the sound are very accurate - I would suggest bringing ear plugs (once I used them the sound didn’t bother me at all).
There were sewage issues with the pipes when I was in the apartment, and the hosts moved me to another apartment within the building so that they could fix the issue (this was after two nights of dealing with the considerable smell). The hosts were very communicative and tried their best to rectify a less than ideal situation. That being said, I would definitely check with the hosts if this issue has been resolved before booking the room.
