I'm the exception to the rule.

I have had the same washer-dryer for 5 years with no problems (touch wood) and i do at least 1 load every day. This washer-dryer was in the house when we bought it, and the owner said he'd had it for over 3 years. So this thing is at least 8 years old, still good as new... washes, dries, and makes my life a lot easier, and my house a lot less cluttered!
But... all the flats ive rented in the past have had either NO washer at all, or *just* a washer with no drying option.
