When we arrived, the temperature outside was 35 C (95 F). We were given a room where the air conditioning did not work. The clerk told us that they have problems in some rooms with air conditioning and told us to move to another room. We did that. Then the whole region lost power, and the power did not come back for hours. When the power came on, the air conditioning did not work. We were told that the hotel has a persistent problem with air conditioning. We are in our late seventies, and as the European experience shows, people our age face a high risk of death in extreme heat. This is not melodrama; this is actually a scientific fact. We did not sleep all night, and we were feeling ill. We kept cool using wet towels. In the morning, we checked out prematurely. If you wish to use this hotel, do not go in the summer. Go at a time of moderate temperatures. Casablanca Hotel is accepting a high responsibility for not providing a warning that the air conditioning does not work properly and for protecting lives of potential patrons. Expedia should demand a statement from their hotels that the hotels they promote have all the necessary safety features.
