I've been a big fan of Tokyu stay (many of their rooms have built in washer/dryer combo), though many business hotels offer washer/dryers in the common areas
some rooms have space with proper desks&chairs, while some are more basic. a few even have stove/fridge/microwave, ~60-120usd/night

EDIT: google maps of the locations, see how close they are to subway station/transport
Really depends on what neighbourhood you want? Or are you looking to try different areas every time? Tokyo's public transit/trains are pretty good and widespread
