Problem: Sentence1: The Alpha-Milton Guest House is in the north part of town at 63 Milton Road. Their postcode is cb41xa. Need anything else? Sentence2: I'm sorry, I haven't found a guesthouse that meets those requirements. Could you possibly stay at a higher rated place, or try a hotel room? Sentence3: Please show me a guesthouse with the lowest available rating. Sentence4: I'd be happy to help you. There are 24 guesthouses to choose from. Is there an area you'd like to stay in, or perhaps a certain price range? Sentence5: I'm sorry, there are no hotels that meet those criteria, either. Would you like to try different star ratings?
