How to arrange the router / routers in the apartment?

Question

WiFi

Good day, there was such a "dilemma". There is a three-room apartment with an area of ​​60 square meters, with a peculiar layout, I have the latest keenetic giga, in a white building. I would like the apartment to have a confident reception of a 2.4 GHz network, and, if possible, of course, a 5 GHz network. In the picture that I am attaching, I see 2 options:
1) place the main router at point No. 1, and at point No. 2 some other kinetic to amplify the signal
2) place the main router at some abstract point No. 3 approximately in the center of the apartment based on the scheme
What scheme the most reliable in your opinion?

Answer 1

Put one normal router in the corridor (3) and it will work everywhere.
The problem is out of the blue.

Answer 2

Put it at point 3, closer to the corner of the wall, it should be enough for everything without any problems, it might be bad to finish it to the kitchen, but it’s not really necessary there, if it’s critical, you can throw the cheapest repeater into the kitchen

Answer 3

IMHO, the plan shows an ordinary three-ruble note, not the royal chambers.
