Pros: this was by far the best hotel of our 15 days trip in many cities in Europe. Staff is the friendliest, hotel location is 100m from the train station and central to everything (coop supermarket 50m away), great view from the mountain, spacious toilet and room, tech room with tablet, mini-frezer, good wifi, beautiful design in both hotel and room. It was fantastic overall. We also had earlier checkin and an upgrade in our room.
Cons: price. This is tricky though, Switzerland is expensive and Zermatt even more. It is hard to give a right number to all the pros above but still the cost benefit is not a 10, is more of a 8-9, which is obviously great
