The Swiss system of room counting might confuse you, probably because it is different from your home country. In the number of rooms it includes: living room, dinning room, sleeping rooms. In the most typical modern Swiss apartment, the kitchen is open to the living/dinning room, counting as a half room.
Examples:
2 ½ room = 1 sleeping room, 1 living room with an open kitchen
3 ½ room = 2 sleeping rooms, 1 living room with an open kitchen
4 room = 3 sleeping rooms, 1 living room (kitchen is an enclosed room)
Most kitchens are already furnished (fridge, stove, oven). Appliances like microwave, boiler, coffee machines are not included. Not every home has clothes washing machines! Some have communal rooms with a washing cycle schedule, others include a washing machine and dryer, and others have the space for it but do not provide the apparatus. Best to ask directly (this information is usually included on the offer).
