First of all you would have to check with your condo association to see if they will permit a washer dryer to be installed. If so, the combo units, like a Mabler, are both washer and dryer in one. They are not vented so they do not use hot air to dry - instead they use centrifigal force. I have used them when I lived in Manhattan and while they are great at light items like underwear, socks and gym clothings, they are not very good for bulky items like linens or jeans. More common are stacked w/d units but they must have a vent for the dryer so whether one can be installed will depend on the configuration of your unit.
