Visited during a warm spell, so understandably, the room was a bit too hot. I guess not many Swiss hotels would bother investing in aircon! The bathrooms need an overhaul - even the grouting and bath panels look a bit grubby. The wifi in the rooms rarely worked for the entire 3-day stay. Plus, the bar shuts at ~11pm, so you get kicked out of the only place in the hotel with working wifi at that point.
The view from the room was stunning (apart from the dreadful monolithic tower block in the town) and the river Aare is a beautiful blue. However, there are many clean cheap places in Interlaken, and unless you plan on using the balcony function of the room (which we definitely did on this trip) it would be cheaper to stay elsewhere.
Staff were very polite and if you have time, the free use of the pool seems like it would be a good experience.
