I was in London in 2004. I just spent about 4 days there and I stayed with friends. I heard that the hotel is quite expensive, I think this is normal as of every Capital cities the pricing is not comparable in the small city.
If my friends didnt proposed to stay with them I think I can find another way to find a cheaper hotel though. I would think of looking for the B&B or other sales on hotel’s reservation online.
What to see in London?
Well, I have seen the London Tower, Tower Bridge, South Bank, St. Pancras Station, Canary Wharf, Westminster Palace, London Eye, Greater London Authority and the Buckinghum palace.
