Great location, with an easy walk from the train. Right in the heart of Zermatt. We appreciated the storage room and boot warmer/dryer, as we were skiing.
However, the free breakfast was very basic, and the woman who manages the breakfast room was difficult to deal with (reminding everyone 5-10 minutes before the breakfast closed, even though we'd been there every day and knew the closing time.) She hovered a bit and was not friendly.
The bigger concern for us was lack of coffee maker in our room. This made it necessary to go down three floors just to get a cup of coffee every morning, but we thought no problem, we'll do it. Turns out - that IS a problem. We were told we could not leave with a cup of coffee and there were no "to go cups." This was very frustrating and inconvenient.
