Ramada London Docklands? Bad hotel? - ramada london docklands

I booked one weeks stay at the Ramada Docklands, London. Suddenly I realized that I have a long way from central London can be removed. My question is very far away? Can I cancel my booking? (Note: I have already paid for the stock could be a refund?)
I would like some answers for those who have stayed at the hotel, or get familiar with the region.
Thank you.
