Stretch from Easky to Bundoran

[michelangelo]

I plan to go for 3 weeks (end of August to mid September) to Ireland (I have never been there before, with the exception of Dublin;-)) and I want to get to know the stretch from Easky to Bundoran. There are many spots, even though I am a bit lost where to stay the best?

My objective would be to stay on a consistent spot so that I do not have to use the car anytime, but it does not bother me to drive around. Is there a benefit in staying in Strandhill, as there seems to be a consistent spot and it seems to be in the middle?
I plan to rent a AirBnb or something similar.

It would be great if someone with local know how and experience could let me know his opinion.
