U: Hello, we're planning on a trip to Cambridge and would like lodging info.  Can you tell us if there is a hotel in the economical range near the centre?

S: Unfortunately, there are no economical hotels in the centre of Cambridge. Would you like to look in a different area?

U: Really? Not even a guest house?

S: Yes, there are no accommodations available that fit that criteria. Would you like to choose something else?

U: I'm looking for a cheap hotel in the centre.

S: There are two cheap guesthouses located in the centre.  My recommendation would be Alexander Bed and Breakfast.

U: Does the hotels have strong showers?
S: Previous guests of Alexander Bed and Breakfast have mentioned having a problem with low water pressure in the shower. Should I check the other cheap guesthouse in the area?
