Adequately large for 4 people, a bit small for 6. Nothing fancy but rather cozy. Apart from the Internet (that wasn't great), and the TV (that didn't work ideally), the other things typically required when a house is rented out (cutlery, sheets, furniture, dishwasher, spacey balcony etc.) were all readily available.
Very kind and available, yet not intrusive home owner.
Given Switzerland's prices, I'd say it's a good offer - the apartment isn't huge or luxurious and it is a bit pricey, but it has all the basic things a guest typically requires and is close to the skiing facilities (Bruson, which is also connected to Verbier's pistes), making it certainly better than many other offers one may find around the area.
