At first there was no hot water when we wanted to take a shower at about 6pm. We asked the front desk and they came quickly and checked the shower and told us to wait for a couple of minutes. However, the hot water still did not come out after about 10 minutes and they went to check the machine but we still did not have hot water after that. We decided to go out for dinner first. They solved the problem after we went back and the water was hot enough though we did not know exactly what the problem was. Make sure the hot water works before your shower!
