What is your experience with non-Leo Palace apartments?

Ones that are like Leo Palace in that they come furnished, and it's relatively a quick process.

I have had experience with Leo Palace in the past, it was good because furnished, only complaint was thin walls and could hear too much from the neighbors (but livable). But I can't find a Leo Palace apartment near where I want to live, and wondering your experience with other ones.

Edit: My only knowledge of different types are LeoPalace, or going to those little shops with the ads on the windows, or YOLO, etc websites (but those websites most of the options are Leo Palace)

Thank you.
