First the location: couldn't be better. Historic centre, facing a really nice square, close to everything. The rooms have different themes, a bit kitsch but comfortable and spacious. The breakfast, while being served in another location (where the reception is located) is good. Great free wi-fi. Not expensive for Switzerland at all.
But it's a fact that the area is noisy at night, you feel like you are in Spain with all the noise people make coming out of bars and talking loud in the street at night. Another strange aspect is that the rooms are very hot even though there is no a/c, so while I stayed at the hotel in late November and might have appreciated the warmth, it was too much so I had to leave the window open to be able to breath, therefore the noise became worse.
All in all, if you get a cheap price it's OK for a short city break.
