U: Hi, I I'm looking for a hotel to stay at that is moderately priced and includes free wifi.

S: I have 17 different options. In order to narrow down an option for you, can you tell me what area you would prefer?

U: I am not sure but I do want it to have a 4 star rating.

S: We have 11 such entries. Does free parking matter to you?

U: Not really, but free parking could be nice.

S: If you have no other preferences to help narrow it down, may I suggest the Acorn guest house? It's very nice, with free wifi and free parking as well.

U: I would also like a room with a high pressure shower, please?
S: They do not have positive reviews for the water pressure at the Acorn Guest House? Should I try a different hotel for you?
