I have a washing machine and dryer. It’s not in my amenities anymore. With that said, I do allow most of my guest to use when ask. However, they must adhere to the instructions I give. it wasn’t always like this, I would get a lot of kids couch surfing, they would search for apartments with washer/dryer. They show up and wash and dry the entire night. They wash pieces at a time. Not only does it heat up my apartment. the electric cost was through the roof. I try to give the benefit of a doubt, however they proved me right over and over. I removed that amenity off my listing. I allow responsible guests access.
