Great little space and you cannot beat the location. The beach is just outside the front door.
Re the house, living area and kitchen on ground floor. Both are well equipped. Stove in the living room in case it's cool in the evening. Upstairs are bedrooms 1 & 2 and the bathroom. Second floor is bedroom 3. Our boy loved the couch in top bedroom and that became the nominated reading couch. Parking on the street outside but we had no trouble getting a spot. High summer might be a different matter though
You won't spend much time there as you'll be busy on the beach or checking out stuff to do/see in the locality. Cynthia sent a great list and this made our trip that bit easier. Plenty of places to eat nearby. Can't go wrong with Roches for dinner and Wild Rose Cafe for breakfast was lovely.
It's good as a base for the area and also if you just want to stay in Duncannon for your whole trip.
