We stayed for three nights, it was great! Very comfortable and stunning views.
The only little problem was the wifi: logging in took a bit of an effort and sometimes it would kick us out.
No complaints about anything else. We especially appreciated the raclette grill, which we used on two of the three nights we stayed there..
The Glacier3000 cable car station is just a five-minute drive away, perfect if you're going there - and you should, it's amazing!
