Most places offer a much better rate for a week or more, so think about how long you want to spend in one place.
How many rooms do you need? How many of you will need a room? What facilities would you like?
What you like to have close to your accommodation? A gym? Restaurants? Night life? Peace and quiet?
Make sure you ask all these questions and more before you make your booking - take your time, choose the perfect location to spend your nights in restfull sleep.
