i owned a two storey cluster house previously also. but i can never use one single wifi router to cover both upstair and downstair even the wifi router for the entire house, anything that further away from the wifi router, even can get the signal and can still use internet, the latency is very high...
i even use 2 x mesh units to cover both downstair and upstair but that time they were connected via wireless backhaul so latency and speed are quite bad still. if u just use it to browse the web and watching youtube etc. maybe not too bad.
if landed house, especially 2 storeys, die die also must have network points on both downstair and upstair to connect the mesh units via wired instead of wireless.

Although my house is a two-storey, it's pretty small with just two bedrooms (it's an old house in SS19, Subang Jaya). So, a single router works just fine for me.
That being said, I totally agree with you on the wireless mesh networking. I wouldn’t rely solely on wireless between nodes. I always make sure to connect them via Ethernet cables, just like I did at my in-laws' place.
I’ll also be swapping the Xiaomi router in my in-laws’ house to replace the Deco M4.
To be honest, Xiaomi's UI is pretty tough to use, and while they’re affordable, it's not up to my expectation. I’ll be replacing it with the ASUS RT-BE86U.
