Tokyu stay is my favorite chain (some rooms have built-in washer/dryer, which makes it very simple for a 2-3 day trip (start wash cycle before u leave for the day, come back with it mostly dry)

Business hotels usually have washer/dryers in the lobby, but u have to babysit it

I did bookmark a couple of dropoff/pickup laundry places in strategic locations (some offer delivery Nationwide), though they are much more expensive but not to the level of hotel laundry service. Need to find those bookmarks
