U: I'm looking for a cheap hotel.

S: alexander bed and breakfast is a guesthouse east of Cambridge center that is cheap, would you like more information?

U: Does it have a star of 4. I don't care if it has free parking.

S: Alexander bed and breakfast does have a 4 star rating, would you like help to book a room?

U: Actually, you mentioned its in the east. I really prefer something in the centre of town thats cheap and 4-star rated. It can be a guesthouse or hotel.

S: The Alexander Bed and Breakfast is a cheap 4 star guesthouse in the centre of town. Would you like me to book it for you?

U: Yes. I'm travelling with my family, so I need a room for 7 people for 4 nights, arriving Thursday.

S: Sorry, that booking was unavailable. Perhaps you'd like a different day or a shorter stay?

U: Is the room big?
S: No, unfortunately the Alexander Bed and Breakfast would struggle to accommodate large parties as the rooms are generally tiny.
