We had a lovely time at this property. We travelled as a family of 5 (children aged 7-12) in July. The house was beautiful (there's actually much more than is listed, e.g. in the kitchen and in the wide selection of games) and very comfortable. The area is stunning - just 2 km from the start of the Cirque Fer a Cheval walks. For running, there are nice routes from the house.
The town of Sixt has nice bars and the Sherpa shop had everything we needed, including lovely cheese and meats. The children loved the activities in Morillon (obstacle courses, treetops climbing, lake swimming, jumping into an airbag). We also took the cable car and chair lift from Samoens. The luge ride at Chamonix was lots of fun!
Carol and Gerry were very helpful and responsive throughout, and the instructions for finding and accessing the property were straightforward and clear.
Something that may be useful to know - a lot of activity centres only take cash, not credit cards.
We had a wonderful time, and would love to return!
