Price performance is not right. Hotel was probably upscale, but is now in need of renovation.
Hotel lives from a good location, room had a very nice view of the lake and mountains - but the mattress was saggy, sofa, coat hanger, hairdryer and floor lamp were defective - lamp must be unplugged because dimmer was broken. Even with all the lights on, the room was very dark.
Overall poor lighting in the whole hotel - light is everywhere too dark, flickering or completely broken.
Choice of food - evening menu and breakfast buffet - is absolutely not suitable for people with intolerances or who value healthy or seasonal and regional or meat or animal-free food. It's all very sugar, fat and meat-heavy. Quality of the food was mixed.
Spa / pool: no corona protection concept, not even notes with max. Pers recommendation for sauna or pool.
Gym: Half of the lamps and devices out of order - cobwebs on the ceilings. Looks like nothing has been cleaned or serviced in months.
Staff mostly friendly and hard-working, but seemed rather inexperienced.
The service manager in the restaurant in the evening was a disaster - he ran into other employees in front of guests, spread a stressful mood and was rude to guests.
We left one night earlier than planned and would not recommend the hotel to anyone: It has various other hotels right on the lake, I would try any other after my stay, but not to the Post Hotel.
