If it is wireless connectivity you are looking at I would look at the Deco M9. The main reason being the M9 has a dedicated wireless backhaul (5GHz). With two units you can get up to 4500 sq. ft. of coverage.

The P9 does have the powerline backhaul, but the quality or speed depends on the wiring quality of your household. 

Given how you are in a apartment, I think a single router may work well too. If you do not care about AX I think the C2300 would work well.

@Alexrat1996 I have a set of Deco P9 (3 units) and it covers our home well at 7,800 sq ft.  However, I think this is overkill for an apartment.  Have used the TO link Archer C7 and C8 in the past with pretty good coverage and would be less expensive and should handle the speeds you want.  On the other hand, if you may be moving to a larger place eventually, the Deco mesh would essentially future proof your setup.
