So after coming up short while looking for a luxury dog friendly accommodation for a lake here in the UK, I'm widening my search to Europe.

I found an amazing little place in France that's cheeper than half the places over here but it doesn't allow dogs.

Any recommendations?

The other issue is that I don't want a lake with big fish. I don't have the kit, ability or inclination to fisher anything over 20-30.
