I stayed at this hotel for a week. Probably due to guests smoked in their non smoking rooms, false alarm rang 5 times at sleep time during my stay. Each time lasted for at least 2-5 minutes. Three times at around 12:00am, two times at around 2:00am. Actually, there were two alarms in one single night, first time at 12:00am, 2nd time at 2:00am. They seemed to have great difficulty to stop the alarm in time. If you need quality sleep overnight, don’t try this one. Having said that, their front desk had been very helpful and friendly though.
