U: I'm looking for a place to stay on my trip to Cambridge. It needs to have free wifi but doesn't need to have free parking.

S: I have 3 places that match your request. Is there a particular area you are looking to stay in?  Would you prefer a hotel or guesthouse?

U: I dont mind either but I am looking for something cheap and located in the south part of town.

S: Rosa's Bed and Breakfast is the guesthouse for you. Cheap, but 4 stars, with free internet and parking.

U: I don't really need parking, is Rosa's in the south of town?

S: Yes it is in the south part of town and has a 4 star rating.  Can I book a room for you?

U: Can you tell me if the rooms have a high clean score?
S: At Rosa's Bed and Breakfast, guests will find rooms that have been exceptionally cleaned by housekeeping.
