We have stayed at Sterretts many times over the last few years,
we love it, but it does have it's down sides, only one toilet near the pitches/one ladies shower and toilet near the wardens home which is further away. No onsite shop,a short drive for any basic supplies.The electric is 10amp and I suggest keeping it to that, we've tripped it many times, and ended up dragging Brian the Warden out at all times.
The pro's are, it's a great area ,very close to the river and within walking distance to several pubs who are friendly and serve good food.
We will be returning in the summer hols.
