We stayed at Gwell Moor over Easter 2021.
Francoise made us feel very welcome and was the perfect host. Even to the extent of dropping us up the Jonah's Restaurant (which incidentally, we found overrated and overpriced).
The studio apartment was beautifully fitted out and the bed was very comfortable. The location of the place was great (but bear in mind it is adjacent to a fairly busy road - which was not a problem for us). As per the photo's on TripAdvisor, the place has an amazing outlook on to Pittwater to watch the sunsets from those lovely wicker chairs. Suggest you park the car on the road to avoid the view being obscured. There is also a swimming and picnic spot just over the road and on an adjacent reserve.
Francoise recommended some great restaurants (Dunes was the standout) and also a great day out to Patonga Beach by ferry. The house is on a bus route to Palm Beach ($1 each way) so we avoided car parking at the ferry terminal and in Palm Beach. The lovely Whale Beach was a short 10 min walk.
We would highly recommend Francoise's studio apartment to anyone looking for a peaceful and fun weekend at the Northern Beaches.
