Cheap price range and a guesthouse.
ok, that helps me narrow it down a bit. Which side of town would you like it to be on
I'm not too concerned with area. Which would you recommend, and do they have internet?

Thank you.  I also need a train on Friday.
I will need a bit more information.  Where will you be departing from and what is your destination?
