This is the way to go - extenders are not very effective.IMO range extenders are a waste of time I've never had any luck with them, power line links work OK but are susceptible to interference, plug a switch mode PS (what most transformers are these days) near them and it kills them.
A Mesh system is the best option, one of the cheaper ones the TP Link M5 works well and easy to set up.
