The toilet in our room ran episodically all night — horrible!
If that wasn’t bad enough, there was obviously a laundry room under our room because whenever the spin cycle ran on a machine, the beds shook for 10 minutes. This happened after we were in bed and didn’t want to deal with contacting the front desk (as we didn’t want to switch rooms at that late hour). Also, we had a very early flight the next morning (the reason we booked the hotel near the airport), so the lack of sleep ruined the beginning of our vacation. Sure would be nice to have a refund for our wasted night!
