If you don't mind sleeping on a sofa bed, you can also rent the house with 6 people. If necessary we can also put a mattress or baby bed in one of the bedrooms (person number 7).
As a tenant of the ground floor you can use the garden (picnic table and lounge set) and, if there is not too much snow you can park your car right next to the chalet (if there is a lot of snow you can possibly discuss with the upstairs neighbours for a place near the garage or else there are also free parking spaces a hundred meters further down).
