The Parkhotel Adler is amazing!! The rooms are great (although each room has a different layout, so…read moreif you don't like the layout of your room, it's worth asking to switch). They have an indoor pool as well as an outdoor pool (both are heated), and you can actually enter the outdoor pool from the indoors, so you aren't freezing if it's cold outside. Their restaurant is right across the walkway, and you can also opt for their breakfast buffet (50 euros/person, so be prepared to eat if you go!). However, the breakfast buffet has quite an impressive spread, and there is also unlimited champagne, so worth the splurge. I highly recommend the Parkhotel Adler!
