Staff was friendly. There was an issue with my reservation which they quickly solved. I was even offered breakfast as compensation. Another positive was that I could leave my bicycle in their underground garage, although I couldn't lock it to something but just to itself.
The rooms, however, were incredibly disappointing. The carpet was dirty, there was hair from someone else on the bedsheets and the bathroom was very small and outdated. Additionally, it was very loud - you could hear every word from the adjacent rooms, their TV and the cleaning staff in the morning.
If this was a very cheap hotel, it would be acceptable, but for the price I paid (200.CHF for a single bed) the price-performance ratio was disappointing.
