Serenity Now is a great well maintained holiday home located walking distance from the beach. It's air-conditioned, has free wifi and a smart tv for watching netflix. Also a good bbq outside (and woodfired pizza oven which we didn't use).
We had 2 adults and 2 kids, but there was room for 8 people if required.
Overall we were very happy. The only issue we had with the location is there are no shops at all in peppy beach, closest shop is 10mins drive away in Capel.
