We live with a family of four and other guests. Downstairs is shared space as there are the (separate) kitchen, living room and toilet. As a guest you can use them all at your convenience.
The house has a front and a back entry. Both can be used. The garden is very green; birds, cats and our rabbits like this space very much. Guests can use the garden as well for wining and dining, just relaxing or to read, work at your laptop an so on.
