U: Can you help me find a train leaving on thursday going to cambridge?

S: sure, where are you departing from?

U: Departing from Broxbourne and leaving after 17:00.

S: TR1828 is leaving at 17:32, would you like to do that?

U: Yes please. I need reservations for two people.

S: Booking was successful, the total fee is 35.79 GBP payable at the station. Reference number is : 8BR3OQ5V.  What else can I assist you with today?

U: Thanks.  I am also looking for an expensive place to stay in the north part of town.

S: Unfortunately, I don't happen to have any places that are expensive in the north. Can I look for something else for you?

U: Could you please double check to make sure? if that's really the case then try the center

S: I'm sorry, but the north does not have anything to meet your needs. There are, however, 2 options that meet your needs in the centre. One 3 and one 4 star.

U: Can I get more info on the 3 star one?

S: Sure, Gonville Hotel is a 3 star rating hotel located at Gonville Place.  It offers free parking and free wifi.  Would you like me to reserve a room?

U: make sure its clean
S: Oh, dear, it looks like some guests had trouble with room cleanliness. Shall I search for an option with cleaner rooms?
