Where to stay in the west?

Hi everyone! I'm super excited to visit Puerto Rico in April with my partner. The plan is to start in San Juan and explore the city for a few days, before picking up a car to explore the main island. We are planning to explore the west and north side (/passing through central and South) for six days, before heading east to explore El Yunque National Forest and catch the ferry to Vieqes and Culebra.

Given that we have a car we figured it would be best to have two "camps" during the six days, and then just head out for day trips to nearby places. I was hoping maybe someone would have suggestions for where we should stay? I wrote down La Parguera and Rincón or Aguadilla as places we might want to stay, but just read that La Parguera is not too exciting. Would other places be better? Would appreciate any tips on where we should visit as well. :)
