THERE ARE NO HOT WATER AT THIS HOTEL!
Rooms do not have basic amenities such as, Iron, blow dryer, and no hot water at all of the hotel! so yes, you will need to shower with cold water!
This hotel doesn't look as nice as in the pictures and it is definitely not a 4 starts Hotel as rated by Expedia!
If you are looking for a nice hotel, it is not the place, it more for a low budget travel.
