The listing fails to mention an important point: that the apartment is not fully separate from the neighbour's apartment. There is a low wall between them, with a gap above the wall.
This means that you hear any sound and smell any smell from their apartment.
For example, when neighbours have a phonecall on speakerphone in their kitchen, it sounds like it is happening in your kitchen.
When they are washing up, cleaning, having conversations, you can hear everything as though it is in your home.
They can also hear everything from you.
This does not allow a feeling of privacy or security that I expect from having a place "all to myself".
