Is there a hotel or bed and breakfast within walking distance from the Celtic Irish Pub?

Yes, there is a Days Inn within a 10 minute walk at 3030 Columbia Pike.

Yeah, a Days Inn is next door...

I made it back to the Sheraton after a night out there.

Go to the Sheraton.

Sheraton is still walking distance. Like a 15 minute walk easy

I wouldn't stay there. Shady place. Get in an uber and go a few blocks more to the Sheraton. Much better.
