I'm looking for a place to stay with free wifi. Find me a hotel like that with a star of 4.
Okay. Would you like to stay on the west side of town, or the centre?
I would like to stay in the south please. 
I'm sorry but I don't have any hotels that match your criteria in that area, would you like to try another part of town?
Can you double check for a 4 star, south area hotel with free wifi and parking please?
I have 2 guesthouses matching your requirements, one cheap and one moderate. I recommend the moderately-priced Aylesbray Lodge.
Okay, thanks. I'm also looking for a train for Friday.
