U: I am going to be staying in north cambridge and need a hotel, I can pay for parking.

S: Ashley hotel is available.

U: Oh, I have heard of that.  Is in in the North part of town?  I am looking for a place in the moderate price range also.

S: Yes is it moderate and in the North side of town. Would you like to book there?

U: Sure, that seems fine.

S: Ok.  What day would you like to book for?

U: Before you book, I just want to make sure--does it have a 4 star rating?

S: No, it is a two star hotel. Could you recheck and restate your perimeters to me?

U: How many stars, area, and price.

S: It's in the north, moderately priced and has a 2 star rating.

U: No, I'm sorry, I should have specified. I need a 4 star place to stay.

S: I'm sorry. I don't have anything that matches your preferences.

U: Are you sure? I need a 4-star, moderately-priced hotel in the North part of town, and I don't need free parking.

S: Again nothing, I could search again but doubt that a new hotel was constructed there during the last couple minutes.  Are you open to a guesthouse or different area?

U: I'm definitely open to a guesthouse.

S: do you need free internet?

U: Doesn't matter if it does to me.

S: We do have some. The acorn guest house is quite nice, when are you planning your stay?

U: Is the acorn in a convenient location to the venue?
S: The Acorn is not very close to the city center so some guests were pretty let down that the nightlife was so far away. However, the guests who were looking for peace and quiet were happy with the location. Would you like to know more about them?
