I couldn’t believe the question when I saw it. Do you also charge extra to sleep on your bed and use your TV? Lol
I would never stay with a host if I have to pay extra for use of the washing machine or detergent etc. And who would want to buy their own detergent when on holiday? Although, I remember using a washing machine only once in my 23 trips.
I provide everything: all kind of cleaning products, detergent, fabric softener, selection of spices, salt, two types of sugar, selection of 8 types of tea, coffee-including coffee machine with a choice of 10 coffees, Starbucks coffee with a French press and instant coffee, shampoo, shower gel, soaps, hair dryer and even hair straightener and lots more.
