With no air conditioning, you're forced to keep the windows open for some ventilation. Unfortunately, there are strip clubs and bars all along the street, and nonstop noise, screaming, honking and talking all night. When the clubs shut down at 5 AM, then the delivery trucks start rolling in. There really is no way to sleep in peace. We went without sleep for 3 days, which really diminishes whatever time you have in Munich.
It's a shame, really, because the staff is great and the property itself is clean and safe. The breakfast was fresh and enjoyable, and they've obviously upgraded the dining room recently. But the location of this hotel drops the experience there to a 3 our of 5. Oh, and the elevator is horrible, so just be prepared to carry your luggage up.
