My family of four stayed very comfortably in this apartment and we would definitely recommend it. The location is perfect. It is quiet, comfortable, and very well equipped. We had a minor problem which was handled with urgency in a high quality way by the owner. If we ever return to Zermatt (and we would love to do so!), we will most certainly try to stay in this apartment again.
I have stayed a number of times at this apartment and can definitely recommend it. I stayed with a couple of friends but I expect it is also perfect when you are with a family. The location is indeed very central and when you get of the train it is literally across the street. Also the restaurants and bars in Zermatt Main Street are at walking distance and the train express that takes you up the slopes is next door. Inside the apartment there are two bathrooms which can be very convenient if you are with a small group and are in a hurry to get to the snow in the morning. Further, the apartment is equipped with everything you need for cooking yourself with a good kitchen and large fridge. In short great apartment to stay!
We loved the place. The owner has clearly thought of everything, Swiss style, and has created a setting in which the guests can fully enjoy Zermatt. My children and I skied all day, and came back to the apartment to cook dinner. (It's a big plus that the supermarket is right below it, so shopping for food is most convenient.)
The furniture is first class, the kitchen is fully stocked, there were even small niceties such as coffee, salt and oil available.
I would recommend this place to anyone who likes living in a home better than a hotel, and wants to save a significant amount of money.
