Fiona's house is better than the listing shows. It's in an amazing location right on the river and only a short stroll up the road to the beach (or a paddle across the river, though none of us were game to try it!). The house was clean and tidy, with all rooms being much larger than the images imply. Multiple living areas mean people aren't all bunched up in one spot.
As a host Fiona was incredibly communicative and took pains to ensure our check-in went as smoothly as possible (which it did).
Pottsville hasn't changed much since I last visited almost 20 years ago. It's a lovely small coastal village, with all the amenities you'll need. The pizza across the road was a welcome find! I highly recommend this accommodation, and I think families with children will find it particularly perfect.
