there are no hotel -s in cambridge that are expensive with a 0 star rating . would you like to change either the price range or the star rating ?
assistant
there s nothing in the north ?

i do have city centre north bed and breakfast in the north . it s in the cheap price range with 0 stars . might that work for you ?
assistant
yeah , i think that would be all right .
user
can i assist you with making a reservation there ?
assistant
yes please for 8 people , 5 nights starting saturday .
user
unfortunately this bed and breakfast is booked for those dates , is there another day or shorter time that would work ? or should we search another area ?
assistant
are there in hotel -s in the north with a 2 star rating ?
user
there are no cheap hotel -s in that area with 2 stars . can i check for a guesthouse for you or would you like another area ?
assistant
i would prefer you to check another area , please .
user
i can not find anything that meets that criteria . we can change the price range or the star rating and search again if you like ?
assistant
can you search for 1 that is cheap in price then ?
user
nothing is rated 2 stars in any part of the city , what specifically would you like ?
assistant
i need something in the cheap price range with other restrictions retained .
