Office Luggage

Hello, Sorry for my English but I am Italian. I come to Washington by bus and I still have one day because a fly in the night. You know a luggage room for free tour of the city?

After September 11, 2001, they were almost eliminated.
You might find one at Union Station, Union Station metro stop.
You may be able to convince a hotel to take you for a small payment.

I know this is not very useful, but it looks bleak.

This is my help from Washington, DC United States of America. Please choose an answer as best answer, even if it is not mine.
