WiFi Project with MikroTik

Dear All,
I hope you all are well, I have a hostel I am providing internet to all my customers through other vendors’ routers Tenda, CISCO, ZTE, etc. but there are 20 rooms in one street. I have attached a picture for reference. So the Room in the front of the router signal strength is good. But installing routers in every room, cable laying and managing are very difficult. So please suggest me a MikroTik 2.4 wireless AP which I can install in the street and covers all the corners of the room in the street.
Waiting for your kind feedback
Thank you

The idea of a wifi signal from outside the building is utopia. It won’t work properly, especially on 2.4
