...we ended up adding a day to our stay, to enjoy the hotel and the nearby Titisee (a nice 2km walk with a footpath in the wood). Excellent facilities, very clean, good food, nice and clean Spa and swimming pool area.
Price isn't the cheapest if you are just planning to stop through a trip, but this hotel is much more than that.
Saig is a really nice village, beautiful views.
Only couple of things not so good: during the evening meal, I ordered a full menu, and my wife just a main course. As my menu had start, soup, main and dessert, they waited my main course to deliver my wife's - which meant she had to wait about 45 minutes from sitting down to eat. Probably our fault not to think it would have happened, yet...
The other thing was that the second morning, with the window open, we had a strong scent of weed coming through our window. I wouldn't have a problem, but wasn't so happy for my little kids and the dog! I ended up checking with the hotel if recreative drugs were allowed in Germany!
Anyway, this is just for completeness, and we would definitely stay again.
