Task-oriented dialogue about: hotel

Hi, can you help me find a 4 star guesthouse?
Certainly. Alexander bed and breakfast and Rosa's bed and breakfast are two of our best kept secrets, offering 4 star quality at inexpensive prices.
Alexander's B&B sounds perfect! Can I book a room there?
What day should I start your booking, and how many days do you plan on staying? Also, how many people would be staying?
Yes, please book for 1 person staying 5 nights starting Monday. Thank you!
Unfortunately, I was not able to make a booking for that. We could try for another day or see if they have availability for a shorter stay.
How about 3 nights?
I was able to book you for three nights starting on Monday. Your reference number is Q8EDDUCC . Is there anything else I can help you with?
No, that will be all. Thank you.
Have a great day then!
