"No matter how many stars a hotel has, one essential is to be clean and in acceptable condition—none of the above. Filthy floor (you could see the stains and smell the odour), old worn out pillows, etc. Moreover, we booked a room for three with a double and single bed; however, we got 2 singles and a bunk bed, which is not suitable for a couple and a baby.
On the other hand, make sure your ID is ready for the police track. Whether you are a local or a foreigner, Spanish hotels require you to provide all your personal details to stay there. No one is innocent unless someone proves otherwise."
