We stayed here for a week - visiting from the old Scotia - and absolutely loved it. The house is convenient for the town and surrounding areas. It is warm and comfortable with plenty of room for a grown-up family - and all the comforts you need - in a traditional - but sympathetically modernised - home.
Michele is a great source of local knowledge - her family having been in St Peter's for generations. She is welcoming but not intrusive - and even offered to cook us the lobster that my daughters were too squeamish to put live in the pot (the lobsters lived to tell the tale - but the offer was much appreciated.)
The walk around the coast is fantastic, and the local community very welcoming. I would have no hesitation in recommending a stay here if you are looking for somewhere good in south C/B.
If you do nothing else while you are here - try the seafood chowder from Charlene's in Whycocomagh - about an hour's drive away. It's available both sitting in and to go. It'd be worth a trip back to C/B on it's own - we but would definitely stay with Michele to do so!
