U: I'm visiting cambridge and I need a place to stay. I'm looking for a 0 star guesthouse.

S: I have two options. One in the north and one in the center. Do you have a preference?

U: No, it should be in the moderate price range and include free wiki, though.

S: I'm so sorry but we don't have anything that exactly matches that.  Since you want a 0 star how about a cheap guesthouse called el shaddai in the centre?

U: what about  the one on the cheap range?

S: Yes I have two options for you. Would you like to book one of these?

U: Yes, can you book for 8 people, 3 nights, starting on thursday.

S: I have made a booking for you for city centre north b and b. Your reference number is K9NGVLIT.

U: Can you please tell me if the bed is very comfortable? I have back pains.
S: I would avoid these beds if at all possible. They are not very comfortable and the mattress not enough support.
