Nice lakeside hotel, but

Nice lakeside hotel, but

1) mattress was too hard. Could not get comfortable at night.
2) pillow was not really comfortable. Only 1. 4* should have minimum 2.
3) very poor wifi in room, only 5MBS. No 4G in the area(Vodafone). Phone signal blocked in dining room.
4) on a main road (Bundesstrasse)
5) all inclusive dining option has no choice. 1 set menu or 1 veggie option.
7) only 1 small hotel bar next to the reception
8) no complimentary water in the room
9) nothing in the immediate area surrounding the hotel
10) only German TV stations. No English, French , Russian, asian or middle east TV. TV not connected to internet.
11) swiss prices
12) came back with diarrhea!
13) best part of the hotel was leaving. That's how uncomfortable I felt.

Good points
1) very clean
2) fish buffet was good, but no potato salad, no French fries?
3) swiss managed
4) room was a good size
5) breakfast was good, but not the best I have experienced at other 4* hotels. Bread selection felt poor for Germany. (Lidl bread rolls?)
6) spa area was nice, 2 sauna, 2 steam rooms and 1 pool and a few showers. Fireplace at the pool was decent.
7) service in restaurant was good
8) traditional blackforest dining room complete with cuckoo clocks (not functioning).
