We liked:
The spacious appartment; the views; the comfortable beds and traditional white duvets
However ...
On hotels.com, it says check-in from 1pm. When we arrived, everywhere was closed up and there was a sign saying check-in from 5pm.
When we finally checked in, we were shown to a fabulous room with top quality furnishings but no kitchen ... which we had booked. Back down to Reception where we had a pretty unpleasant conversation with the owner who said it wasn't his fault etc. After 10mins of this, he showed us to an apartment over Reception. It was huge: three bedrooms and a separate living-dining room plus a kitchenette. We breathed a sigh of relief, accepted that he wanted us to pay 15€ extra per day, and set about unpacking.
"Mein Frau" came to make up the beds and told us not to use one of the bedrooms. Which was fine, we didn't need it but her manner wasn't very friendly.
When she'd gone, we discovered that although there were 12 cups and saucers, there were no bowls or plates. There were no pans and the kettle leaked from the bottom. We were too tired and fed up to say anything else.
Overnight, we were disturbed by people coming and going - patrons of the restaurant, staff, deliveries etc. There's a road running between the two hotel buildings. It is unbelievably busy and noisy with locals: tractors, scooters and speeding cars and we had 3 nights of disturbed sleep.
We were sad to leave the area and think we were unlucky with Gasthof Adler
