Does anyone know of a full-service laundromat in Berlin? I will be staying just southeast of the Tiergarten on Leipziger Strasse.
There will be one in your area since it is there for the locals. As for directions from where you are staying. They are the best source for that type of information.
If you take a Fat Tire Bicycle Tour you can pay them to do your laundry while you're on it. We did this and it was great! You might be able to pay them to do it even if you're not on the tour, but that would be way less fun.
Thank you all for the good tips! This is very helpful.
