@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.
