Hello, are there any centrally located hotels in Cambridge with free parking?
There are a few hotels that meet your criteria. Would you be interested in the Alexander Bed and Breakfast? It has four stars with cheap prices.
The hotel should be in the expensive price range.
There are 2 hotels in the expensive price range. One has 3 stars and one has 4 stars.
Let's go with the 4 star option. I'd like to book it for two people and three nights starting from thursday.
Booking was unsuccessful. Would you like to book another day or a shorter day?
Please try to book a 1 night stay.
The booking was successful at the University Arms Hotel. Your reference number is: E7AK16IK. Would you like the phone number?
I also need a restaurant the restaurant should be in the expensive price range and serve north american food.
The only result in your area meeting that criteria is Gourmet Burger Kitchen in centre. Would you like me to book a table for you?
Yes please book the restaurant for me.
Not a problem. For what time and day will that be for?
I changed my mind. I will go ahead and book it myself. But, can you please provide me the address and postcode. Thanks.
