U: Yes try a different area.

S: Would you like to try a hotel on the west side of town?

U: Sure, I think that would work...as long as there is a lot of public transportation around.

S: There are two hotels that meet your needs. I highly suggest the Cambridge Belfry. Yes there is public transportation.

U: Are the rest rooms clean?
S: Not according to the reviews.  Previous guests stated that the bathroom was so dirty they felt uneasing even using it because of all the germs.
