"it was an "almost" perfect experience .....everything was perfect ...till for some mysterious reason an obnoxious Sirene like sound , steady but dull in intensity started in the room in the middle of the night, which of course it woke us up . We couldn't find out the reason for it and how to stop it . By the time , out of frustration , were about to call maintenance the sound stopped. But that created enough stress and adrenaline that we couldn't promptly fall asleep again . That ...kind of ruined the overall ,perfect experience . Front desk has been notified ."
