THE FUSE

For mesh routers with two nodes, I place the first in my living room, connected via ethernet to my cable modem with the second on the first floor landing in the (ostensible) center of the house. For three-node sets, the third goes in my kitchen, which I've found is the optimal layout to get the bulk of my house covered in Wi-Fi. Fundamentally, my home poses enough challenges that if it succeeds here, it stands a very good chance of succeeding in your place.
