The host didn't allow us to use heating system as expected. he said the ernergy cost is very high . He said I could turn on the heathing system when I checked in. But in fact he turned it off only a short while after I turned it on every time. The host said "I SAID DONOT TURN ON!! " in a threatening tone even at 4am in the last day. The room temperature is quite low. Only electric blanket can help a bit when we slept,but not comfortable. we caught cold, had to buy medicines and see doctors in the following days, we had more than 3 full days that my poor child had to stay in hotel room due to high fever. All activities in the trip were distrupted.
