U: I am looking for a hotel to stay at in Cambridge, at least a 4 star place please

S: I've found 3 total entries for what you're searching for. The hotels are all 4 stars and ranges from cheap to expensive. It can be filtered down more to include prices.

U: are any of them on the north side of town?

S: No, sorry. Would you like me to try searching for something else?

U: Can you check the north side for other hotels?

S: Yes I can search for other hotels, do you want to change the star from 4?

U: i'd prefer a 4 star in the north

S: I'm sorry there are still no matching results. I can try a different part of town if you would like.

U: Is there possibly a guest house?  I need free parking also.

S: There are a number of guesthouses in that area with 4 stars. Do you have a price preference?

U: No, no price preference. What do you recommend?

S: I'd suggest Acorn Guest House. It is a moderate priced guesthouse in the north with 4 stars. Would you like me to book any rooms?

U: Is there a stable internet connection? It's very important to me.
S: Reviews of the WiFi at Acorn Guest House are positive. Can I answer anything else about this location for you?
