"Costly and lengthy trips to the laundrette because the apartment doesn’t have a washing machine."
This illustrates one of the first understandings about renting Airbnbs: open the list of amenities to see if the place has what you need and want.
A washing machine is always on my list. If the place has none, I look for another place. In hot months, I look for an air conditioner.
