Matthiol is literally at the end of Zermatt (towards the Matterhorn), which means a 25 minutes walk to town. Fortunately, they offer free transfers upon arrival and departure. The setting is wonderful, they have a small lawn in front of their building where we had breakfast and dinner outside. Unfortunately, you can only see the Matterhorn from the upper floors and not from the lawn. Their staff was very kind and friendly, we also very much enjoyed the (small but good) breakfast and also had dinner twice in their restaurant. The best was our room, with its own small sauna and a small hamam integrated into the shower. They have a small wellness area and an outside jacuzzi as well, but our own had views of the Matterhorn and we thus preferred that compared to the slightly dark common spa area. We also made extensive use of the free-standing bathtub in our room that had an excellent Matterhorn view as well. Overall, this place is wonderful if you book one of these spa rooms. If you don't, I would probably prefer a place closer to town that has a bigger common wellness area, i.e., also with a pool.
