Are there any guesthouses in the north area of town?
We have 11 guesthouses available.  Is it possible to narrow it down to price range or number of stars?
Yes I am looking for something in the expensive price range.
We have no guesthouses in the expensive range, are there any other ranges that you would be interested in.
