It's the end of July and it's hot in Paris. So being smart, we chose the Cardinal Rive Gauche, a hotel that claims to have climate control. But contrary to our expectations, we went to bed at 11pm at night with sweat dripping from our foreheads. There is are signs of air conditioning: a thermostat that we set to full blast and a vent from which relatively cool air flowed. But our top floor room had absorbed the strong afternoon sun, and the weak AC system could not make a dent in the heat.
Of course, we complained to the nice woman at the front desk, and she said that the hotel's air conditioning system was indeed not strong ("forte"). She suggested that we open our windows later in the evening to let in the cool air. So we waited until 9 pm to open the windows only to be disappointed by a lack of cross-ventilation. The heat-loaded walls continued to bake us, and we awoke too tired to enjoy our second day in Paris.
Other less serious problems: Two of our lights had bad bulbs, one night light and the overhead light. The bathtub drained very very slowly and so one was left standing in two inches of water after taking the shower.
The person at the reception was very nice and eager to help. Unfortunately, this person
had no help and was overwhelmed by the demands of the hotel's guests.
We waited 15 minutes to check-in and, later, 15 minutes to ask a simple question.
